Ikenna

I’m not looking for cures. Just insight on what could be happening to my heart / body on a physiological level. Formally diagnosed with POTS / Autonomic Dysfunction (from 3 cardios and 1 neurologist) Blood pressure normal, BPM controlled on Beta Blocker, on standing I don’t faint, I don’t get dizzy, I do get tachycardia if not medicated, I get blood pooling. Medicine: Midodrine 10mg, Atenolol 20mg My BIG problem is that: I simply can’t tolerate adrenaline. Whether it be an argument, playing a video game, being startled, ANYTHING sexual, standing for more than a few minutes (POTS), exercising, being in cold weather or water. Anything that would normally release a good dose of adrenaline destroys my heart. My heart will get sore (not general chest area, but left side, only around heart area). When it is sore, my heart is 2-3x more sensitive to adrenaline until the soreness wears off. Which takes anywhere from 1h to 2 days. The soreness renders me bedridden as I can’t do any activity that would worsen it while it’s present (walking included - sad face). Examples (explicit): Walk for 10 minutes -> heart sore for 3 hours. Masturbate for 2 minutes -> heart is sore for 5 hours. Do 20 pushups -> heart is sore for 3 hours. Get into major argument -> heart is sore for 2 days. The more taxing / adrenaline releasing an activity is, the longer my heart is sore. On a physiological level, what could be happening? It seems like severe beta (or perhaps alpha?) adrenergic hypersensitivity on my heart that renders it sore (perhaps something else). That sensitivity is then increased after a stressful event and renders my adrenaline receptors even more sensitive. In a vicious loop. Only time resets my receptors. I’ve read 1000+ posts from others with dysautonomia / POTS and have never heard the same as I described here. Hopefully someone knows what’s going on internally? I would have bet a beta blocker would prevent the soreness but it doesn’t seem to. Granted I’m on standard low dosage (Atenolol 20mg).
