Rollercoaster, or going down a hill like sensation

My dad has been having these types of sensations, and I want to find out what the cause is since the symptoms are so hard to describe it's difficult to look them up and find anything. He feels the sensation of being on a roller coaster or going down a hill without actually doing so. We went to the heart specialist and she performed a test on him, and found out that his artery was clogged. He went through a procedure to get his artery unclogged, but the sensation persists, and he says it's unbearable. He was prescribed 5 different medications for blood pressure, and his heart. I looked up his symptoms which are difficult to look up since his best description is what one feels when they go down a hill something like a rise, and what I found is that the cause is likely anxiety. He doesn't always feel this way, it's like something random. Like you're doing something, and then suddenly you feel a rising sensation, and it goes away. This happens to him constantly. He says it happens to him while he's standing up, sitting down, and laying on his bed, but he told me it happens most often when he's laying on his bed. What should he do? Any recommendations on what doctor he should visit? Has anyone else felt these symptoms, and found anything that helps?

Not just "I found something I enjoy more" but rather "oh HELL no."

Like...being in a class where you learned that it wasn't uncommon for bugs to burrow into eyes or something, and realizing you'd have to deal with that made you realize that maybe you're fine dealing with people coughing up lungs but not THAT. So you switched to podiatry because at least the bugs in feet are less scream-squick.

Hi everyone! I’m a 23m, 5’6’’, 140lbs, from Brazil. I don’t smoke or use recreational drugs except for alcohol, which I drink less than once a month.  Before January 2024, I was completely healthy. I worked out daily—powerlifting and HIIT—and had no heart-related symptoms.

Then I got COVID (mild fever only), and my life turned upside down. I’ve been struggling for over a year with unexplained heart symptoms, and I’m desperate for guidance.

Story:

After recovering from COVID, I immediately started experiencing constant pain and tightness in my chest, as if my heart was struggling to "catch its breath," along with painful palpitations that felt like sudden, heavy thuds—especially when walking. This was accompanied by shortness of breath, tingling in my left hand, and a feeling that my leg was swollen.

Scared and desperate for answers, I went to the ER five times, but they performed ECGs, blood tests, and X-rays—everything was "normal."

Since then, while no longer as overwhelming as the initial weeks, the symptoms have never completely gone away. They only “stabilize” and are triggered again by minimal physical exertion, such as cleaning my room. When this happens, the symptoms last for days or weeks, and I need extensive rest to feel better.

These symptoms now include:

• Chest pain and shortness of breath
• Tachycardia (120–150 BPM) upon standing/heat exposure.
• High blood pressure
• Very weak and shaking legs
• Fatigue that makes it hard to get out of bed

Even on days when symptoms are not triggered, I still deal with a milder version of them. Rest helps, but I’ve never had a single day since COVID where I felt like my old self.

ADHD Medications:

I’ve tried stopping my ADHD medication (bupropion XL 150 mg) for three months, suspecting it might worsen or even cause my heart issues, but saw no improvement. Recently, I restarted treatment with lisdexamfetamine (Venvanse) 30 mg and have been able to manage my ADHD without overall worsening of cardiac symptoms. However, I still pause it during flare-ups out of caution, worried it could aggravate my condition.

Tests I’ve Done (all "normal")

Blood tests: No abnormalities detected, including troponin levels, which were within normal range.

Echocardiogram: No significant changes, only a minor tricuspid regurgitation noted as within normal limits.

24-hour Ambulatory Blood Pressure Monitoring (ABPM): Showed elevated and fluctuating blood pressure readings, which was not a previous issue for me.

24-hour Holter monitoring: Recorded a single isolated arrhythmia. However, the report noted my heart rate reaching 150 bpm while at rest, which I find quite unusual.

Cardiac Magnetic Resonance Imaging (MRI): No abnormalities detected.

Chest Computed Tomography (CT) scan: No significant findings except for "minimal pleuroparenchymal interface irregularities at the lung apices, likely residual in nature."

Frustration:

Living with persistent, undiagnosed symptoms is deeply frustrating. My life is on hold: simple tasks like cleaning my room worsen my condition for days, and forced rest steals my independence. I find no clear causes in tests, yet the physical discomfort remains real and debilitating. The lack of answers gives me anguish—without knowing what’s wrong, there’s no clear treatment or hope for improvement.

Some doctors have suggested this is anxiety and that I should “just forget about it” and resume normal activities. However, after months of therapy, both my psychologist and psychiatrist agree there’s no psychological basis for these symptoms. They only happen after physical activity, never during emotional stress.

Questions:

1. Could this be something tests can’t see? I’ve read about "microclots" or hidden inflammation after COVID. Is that possible even if my blood tests are normal?
2. Can tests give false negatives? For example, if I had myocarditis, could the echocardiogram miss it if done too late? I took this test one month after symptoms began.
3. What else should I try? I’ll do any test or see any specialist—I just need a direction.

Conclusion:

I’m not looking for a diagnosis, just… ideas. Anything I can take to my doctors here. I’m scared this will never improve. If anyone has seen cases like this, please share your thoughts.

Thank you for reading.

I’m thinking of starting a research-focused community for medical students and residents to learn, collaborate, and improve research skills. Topics would include study design, biostatistics, manuscript writing, and more.

Would you be interested? What topics or features would you find most useful? Let me know your thoughts!

I'd like to stay as anonymous as possible, just need some general advice.

Back in 2018 i caught one misdemeanor charge for paraphernalia. Had the case expunged and it never haunted me again. I was able to answer "No" to criminal background checks for the last 7 years and it's as if it never happened. It worked for college and my medical school admissions. Now I'm a second year, already with my STEP 1 scheduled and upcoming, getting ready to schedule my 3rd year clerkships. I have to do another background check, but for some reason I am paranoid and I think that this background check may be more intensive than the medical school's because it is a hospital and not a learning institution. Is this true or just a paranoid thought? I wouldn't even know how to get records or information on my case because it happened so long ago. Before medical school admissions I tried to search for my case, and I couldn't even find it anymore. Any advice here is appreciated from anyone, especially if this is something similar you have gone through before. Thank you.

I’m pretty confused but I got a total ingrown removal with acid too and he says to remove bandage after 7 hours (while it’s still sorta numb) and clean and change it, is this safe to do because everything I’ve read says to NOT remove it before 24 hours

Hello!

I’m a third-year psychology university student, studying at Goldsmiths, University of London, and I am working on my dissertation project this year. My dissertation will be on investigating how medical students experience and cope with stress.

I am looking to recruit medical students (currently studying in the UK) who have experience with stress. I will be conducting online interviews on Microsoft Teams. I have attached a recruitment poster in this post. These interviews will take place in January and will take place on days when both the researcher and participant are available.

If anyone would like any further information, or is interested in participating in this study, please contact: Jenny Dishnica (jdish001@gold.ac.uk).

I would be incredibly grateful if anyone would like to take part!

Many thanks.

Before I begin, moderators I am not seeking medical advice. Please don’t remove this post.

My Brazilian Jujitsu  journey started via Mixed Martial Arts, around 14 years ago when I was 30. My lower discs started to give me some issues at the age of 35, so I decided to only focus on BJJ, since it was more easily accessible, and kinder to my body.

I loved BJJ so much, I trained around 5 days per week for 2-3 hours per day. Then an undiagnosed injury paid me a visit.

I picked up a groin injury, and decided to train trough it. That was a bad idea, since the discomfort of the injury began to affect my inner thigh approaching the knee, and forced me to take a short break. That short break turned into 3 years.

Numerous doctors assessed my issue and couldn’t find anything via x-rays and MRI’s. One doctor told me I’d never be able to train BJJ again.

I felt I recovered after 3 years, and decided to test the water in 2022. I was wrong and a little discomfort reminded me it’s not safe to go back in the water.

Now 2 years later, at the age of 42, I feel I have recovered, and am planning to return to BJJ. Is it safe? Or am I finished?

She has 17*17cm fibroid , therefore doc recommended removal of uterus , I have to take care of her after surgery, so I need little guidance

2 - what's the best way to arrange urination and defication and bathing , without making her too uncomfortable as I am he only son and don't have any sisters 3 - any other things I need to keep in mind

Is there anyone who studied medicine in English in Italy and got overseas to USA for the last year as an international non eu student to answer some questions regarding to the process?

I got my x-rays and have an appointment with an orthopedic today evening. While I wait for it, I really wanted to know if the angulation here is bad enough to require a surgery? Is it possible to heal correctly with splints only? Any reassurance that surgery won't be needed would be extremely helpful!

Hi everyone,

I would like to gain more insight into the bare below the elbow policy concerning the following practical situations in America, Canada, Australia, and Europe:

• When someone has skin damage or a skin condition such as eczema or psoriasis.
• In situations where the risk of scratches is high, for example, in geriatric wards.
• Or when healthcare providers need to cover their forearms for various reasons, such as cold environments, religious beliefs, body image, etc.

Are these needs taken into account? Or are adjustments made in consultation with infection prevention departments that meet the needs of healthcare providers while still adhering to hygiene rules and bare below the elbow policies?

I searched online and found that, for example, in England, there are antibacterial sleeves that can be wiped and worn. Does anyone have experience with these?

I’m curious to know if such adjustments of the dress code are allowed and available in other European countries as well.

Thanks alot!

Some time ago I fell apart with my peers and friends from college, and went out of practice a couple of years because of crippling burnout.

I tried 'getting back in' during COVID, which was probably not the best idea in hindsight, because after 2 years on a hospital my burnout came back harder, so I changed area to consultant for an insurance company, which had an amazing pay, yet was emotionally demanding to watch how the company I worked for was all about the money, not regarding the wellness of the patients we insured. So I left that job, and the city about 6 month ago.

Recently I started a medical clinic in a small town (900 habitants) I'm currently living in where I can practice under my own terms, so there's that. But other than myself, there aren't any other doctors nearby to bounce off ideas and projects.

I have time during the day to tend for the land and animals on my homestead, yet I feel I could be doing more other than be sitting in the clinic to make use of my profession. How do I start doing research? How do I find news on the latest updates and science?

I can't invest on formal education at the moment because I'm really short on funds.

i’ve been having back pain pretty consistently going on like three years now. it started after a bad squat in the gym and i slipped a disc in my lower back. i’ve tried a lot for it - PT, Massages, Gabbapentin (bad reaction), NSAIDS, etc. nothing has seemed to really help aside from when i take like 4 advil, but only helps for the duration the advil is in my system.

i feel at a loss for what it could be. the pain moved from where it initially started (lower back and sciacta in my leg). it heavily affects my everyday life and i’ve gotten an MRI already for it which came back clean. it feels like a super intense muscle knot that aches all over my back and i can only get relief from bending over and pulling my arm over me (stretching rib area). i’ll leave an image illustrating where im feeling it.

i feel like i can’t find any help or clue of what it can be. i started medicine for anxiety because i believe that does make it worse, but it seems to randomly improve sometimes - but mostly im always in pain. im 20 and feel like ive been mostly bed bound since i was 18 and like i cant live how i want at all.

Hello, about 5 days ago I fell over on air and scraped my knee. It looked fine the first few days, but has just gotten redder and angrier overtime. Nothings helping and I can’t even move my knee without pain, I’m super confused

The majority of patients may safely take glucagon-like peptide 1 receptor agonists (GLP-1 RAs) before elective surgery and gastrointestinal endoscopies, according to updated guidance from five medical societies.

The new guidance, contrasting with earlier recommendations, says these read more..

A 12-year-old boy with cystic fibrosis (CF) presents to the emergency department reporting persistent, worsening abdominal pain and diarrhea for the past 8 weeks, as well as acute-onset vomiting for one day.

His CF has been complicated by pancreatic insufficiency, poor weight gain, and CF-related diabetes requiring insulin. To attain adequate nutrition for catch-up, he eats three full meals and three snacks daily. His pancreatic enzyme replacement therapy consists of 10,000 units of lipase/kg/meal and 5000 units of lipase/kg/snack. Three weeks ago, he completed a course of cefazolin for a respiratory flare of his lung disease; it was his second flare requiring intravenous antibiotics in the past 3 months.

His medical history is also notable for acute appendicitis requiring appendectomy at 6 years of age, gastroesophageal reflux disease requiring omeprazole 40 mg daily for the past 6 months, and constipation requiring senna 15 mg daily for the past 6 years.

On examination, the patient appears ill. He weighs 31 kg, measures 144 cm, and has a BMI of 14.9. He is afebrile, tachycardic, and normotensive. He has tenderness in the right lower quadrant and guarding but no rebound. Bowel sounds are diminished, and there is mild abdominal distention.

An abdominal CT scan reveals thickening of the ascending colon wall with narrowing of the intestinal lumen and loss of colonic haustra. Mild ascites is apparent with no intestinal air-fluid levels.

Which one of the following components of care is most likely to have put this patient at risk for his current symptoms?

1-Proton pump inhibitor use 2-Inadequately treated constipation 3-Excessive dosage of pancreatic enzyme replacement therapy 4-Prolonged use of a stimulant laxative 5-Recurrent antibiotic exposure

Idk if this is the right subreddit to ask but i believe someone in here might have experience with research careers and all and i was interested in researching the human body and stuff related to it especially regeneration and immune system so can somebody tell me if research scientist in the field of regenerative medicine is right for me or not(i didn't knew what tag to put so i just put research since it kinda related to that so please don't be mad)

As cancer cells grow, they pump out metabolic byproducts such as lactic acid into the tumor microenvironment. Exhausted T cells -; which have lost their cancer-fighting oomph -; consume this lactic acid, which further saps their energy, according to new research from the University of Pittsburgh and UPMC Hillman Cancer Center. read more...
