For 6 weeks my 20 year old daughter suffered with severe abdominal pain, constpation,nausea, and vomiting. Many doctors 2 hospitals and told after much drugs and testing it was all emotional.
Finally a resident listened to her and gave her a blood test and a tilt-table test.
She has Post-viral autonomic neuropathy with Addison's disease!
1.5 pills a day and she's feeling great!!
Don't give up. Go to a teaching hospital and talk with the young dr.s
They welcome a challenge.
