Feeling much less out of breath and no chest tightness
Another update to pyridostigmine: As of now I can confidently say it's "cured" my symptoms. I'm at 30 mg TID and my HR while standing has reduced from 120+ to 75-85 (55-65 supine), I feel much less fatigued, no chest tightness when standing, no lightheadedness, no nothing! Got a massive boost in quality of life. Very happy I decided to take it, hope it doesn't lose too much effect over time.
I guess the next steps down the line will be to slowly wean me off the other medications (midodrine, fludrocortisone, nebivolol) one by one in the following months and see if the symptomatic relief through pyridostigmine sticks or if it's a beneficial interaction between anything in this cocktail. Let's see what my cardiologist says.
Do you have a PoTS diagnosis? Or dysautonomia / OI?
Mixed POTS and OI. No "classical" dysautonomia symptoms such as GI issues or dry/watery eyes/mouth, according to my doc.
What exactly is up, is probably a mystery tbh.
Did a beta-blocker help you? Propranolol 20 mg in the morning seems to help lower my HR but doesn't seem to do much else to help my OI (which isn't severe, but is still quite disabling during PEM). I may trial mestinon.
Have you been tested for antibodies against the acetylcholine receptor. If not it might be worth doing so.Another update to pyridostigmine: As of now I can confidently say it's "cured" my symptoms.
Thanks for the tip, yes I've been tested and no autoantibodies against acetylcholine receptors found. Also no muscle weakness as it would present with MG.Have you been tested for antibodies against the acetylcholine receptor. If not it might be worth doing so.
Just a boring update: It's still working very well. Standing around 80 BPM now (from 120-140 bpm before treatment) - quality of life greatly improved.
