My 16 year old son has been sick for almost 2 years. When we finally had the endoscopy/colonoscopy he was diagnosed as having a stomach ulcer, hiatal hernia, GERD, and Crohn's. Since then he has PUT ON about 50 lbs so the Dr is now thinking he may have been misdiagnosed and won't treat him for Crohn's. He vomits for days on end and has chronic, painful diarrhea (around 10-12 or more times daily). Other symptoms include severe abdominal pain (right side), painful joints, headaches, and rashes on his torso and arms. He has been on medicine for his ulcer and GERD for over a year now, yet he still spends a couple days a week vomitting 3-5 time a day. He has been sick so long that he missed most of his freshman year of high school and I am homeschooling this, his sophomore, year. Please help with any advice or other things we should look into.
