My husband has been in & out of the ER 15 times in the past 6 mos. with the same symptoms...which the dr's have no idea what is wrong with him...they keep coming to the conclusion of anxiety. He wakes in the morning to have a BM and if its diarrhea he begins to violently vomit, sweat heavily and has severe abdominal pain where is stomach is very bloated. I take him to the ER where they administer atavan and dulantin (not sure of spelling), within an hour he is back to normal. He's had an endoscopy twice...they found nothing...a ct scan...they found nothing....a colonoscopy...they found nothing...tons of x-rays and blood work and nothing turns up. the GI dr. he's been seeing has put him on klonipin and nortriptyline. he said the nortriptyline is to help repair his vagal nerve repair itself....i just want to know if there is something else we should be looking at that could cause these symptoms and if nortriptyline is used for that because everything i've read about the drug says its an anti-deppressant
