I do experiance something called orthostatic hypotension,, ie feeling faint if i stand up to quickly especially if i have been working out and have tight leg muscles.. i have learned to stand up slower,,, i also went to a cardiologist for heart palpatations,, i wore a monitor for a month and what she saw didnt concern her although i have had them to the point where i do feel faint,, and sometimes have dirreaha with them so sounds like we have a similar issue

My hand is up! Yes!! It was one of my first symptoms and one of the first symptoms that could be empirically measured! I was diagnosed with "The Gold Standard:" The Tilt Table Test. Boy did my doctor start treating me more sensitively and seriously after that! Up to that point, I had "general malaise," "debilitating and chronic fatigue," "slight cognitive issue of concentration impairment, and depression.

It's why I recommend testing for mediated hypotension when someone feels dizzy or slightly nauseous with no known reason. At the very least, you get one facet ruled in or out which is crucial in the detective game of medicine.

Hope this helps.

To answer your follow up question... I was encouraged to eat a lot of salt. Even mix it with water and drink daily. When I asked him for a more livable solution lol, pun, he prescribed a vasoconstrictor now called mitodrine. 5 to 10 mg every few hours. It was a game changer! It absolutely reduced the facet of depression that was caused by inactivity and mental fatigue and I could function much more normally.🤗😎

But I can tell you something that may be of tangential relevance and that you may want to check out because
vasoconstrictors aren't safe for everyone ... down the road researchers found that a significant number of fibromyalgia patients have slight cardiac arrhythmia. I happened to have a preventive work up and neither my referring doctor nor myself had ever noticed anything unusual. But the cardiologist was older and very experienced and he detected it. He said that he would have missed it as a younger doctor but he'd learned to listen to something in particular and he caught it. In his experience he said it didn't denote any negative consequence so it was a benign characteristic but of course that may change as researchers gain more info.

Did I have this as a child or did it develop after having fibro and would either option signify something? We don't know yet.

My problems are definitely related to my gut as well. When my stomach flares up, I definitely get more symptoms of rapid heart rate and feeling like I’m going to pass out. I’m not sure if the the gut issues cause the autonomic problem though or the other way around. I also saw a gastroenterologist and did an upper endoscopy... it didn’t find anything significant.

And Teresa, I am also super sensitive to medication! If the medication lists a side effect, there is a pretty good chance I’m going to get it! But occasionally I do tolerate a medication, so it’s always worth trying...

Yes for hypersensitive to meds. Most of us on here report that. We end up with a lot more allergies and dermatologic issues over time (rashes, etc) too. Lots of neck and shoulder/upper body pain. Insomnia. Like a grocery list. Only not.
