Hi. I need to ask if anyone else experiences something similar. To let you know, I recently have seen an neuro who says it appears I have dysautonomia (his guess is "immune-mediated") and am scheduled for my autonomic testing later this month. Here's my whole long story: first ever episode started last november on vacation. acute onset of dizziness, panic feelings, extreme heat and a headache, then my body proceeded to purge itself of eveything inside it and i started with full body temors. after a little while my body would go into "recovery mode" as i call it - extreme exhaustion where I can't really talk and move - for a few minutes and then the cycle starts again. This lasted for about 2 or 3 hrs. ER doc said I had laberynthitis and sent my home. Stayed dizzy and nauseous and within a week had a raging sinus infection and double ear infection. In about eight weeks my infections and other symptoms cleared. I thought it was all done. I did continue to be sick with everything my kindergartener brought home from school until May. In both January and April i had smaller versions of the episode that happened in Nov - they were much shorter in duration and not quite as severe. Then in June had another big one and since then I have daily symptoms like dizziness, nausa, GI issues, BP jumps around, I'm orthostatic (but never passing out), blah blah, all the things you know about all too well. But just within the past month I have had three more of those really big bad episodes, just as described above. Haven't seen a pattern or trigger. I can tell when they are going to happen, like and animal can sense an earthquake and i just "ride the wave." But i want to know if anyone else experiences something similar? I'm curious as to why I'm having more? The neurologist i saw put me on Mestinon which seems to have no bad side effects and has made it so I have good parts of everyday and no more GI issues. On to the next batch of testing... Any thoughts for me? Thanks.
