Hey, I don't know if anyone is still watching this, I happened to come across the description of your symptoms, and they are almost EXACTLY the same as mine. I'm 24, 6"3' 180lbs. Also slightly high blood pressure
ranging from 140/80 to 170/90 at several different measurements. Hyperhidrosis of palms and feet developed when I was approx 14 and gradually got worse and developed in generalised HH. Also had various blood/urine tests for phaeochromocytoma, carcinoid
, diabetes, all came back negative (after initial false positive for diabetes). Full body MRI and chest X-rays also negative. I had botox injections a couple of times, used several meds including oxybutynin for a short while with no real success. Now off meds for appr. 1,5 year, but still have GI symptoms, loose stools, abd. bloating as well as cottonmouth especially in the morning but also while talking much or playing sports that I too originally wrote down to the meds. I wake up a lot at night too. I feel I have more trouble with joint pains as I should as well but I can't be sure they are abnormal or if everyone has them, they do temporarily subside with exercise. Had problems with my nose
infection once, nasal voice, always rediculous pain with pressure differences when the plain descends). Quite a list, but unfortunately true.
Differences are that I didn't do the roids and I don't work in a dusty environment, from Europe in fact, so this thing crosses continents. In the off chance you're still watching this did you get any further? I'm thinking about seeing my GP to get a coeliac test but feel like it's something different.
