I had the same symptoms of sweating every day and fainting! Also, my digestive system was messed up. My doctors could not figure out what was wrong. Sent me to GI, Endo, Neuro, pain management. Very frustrating until I went for a Hida Scan for my gallbladder. They gave me CCK(hormone) IV and all my symptoms disappeared. We finally figured out it was my vagus nerve, possibly damaged and causing these problems. For some reason the CCK calmed down everything. So I researched the vagus nerve and what to do and I am almost symptom free!. I use a tens unit for the ear, you can purchase on amazon, I try to snack all day or chew gum, this releases CCK, meditate, take deep breaths and smell lavender. Believe me all this has helped. I did so much research on the vagus nerve and CCK that all my doctors asked me for a copy of my notes! There is no harm in investigating and trying. I really thought I was a NETs patient, but thank goodness not. Living a better life after years of dealing with all these symptoms and so many test. Good luck and never give up. Be your own advocate and keep searching. You would be surprised how you can heal yourself.
