Hi there, I was so happy to hear someone elses story thats just like my 18 year old sons. We went through 3 years of hell with dermatologist, center for infectious disease, shands hospital, allergy tests..you name it. finally figured out it was a gluten allergy, also dairy. I would love to talk to you in length about this nigjtmare and maybe we can help each other. I also just took my sons to a GI doc. One month ago. His biopsy was negative. Its wrong. Hes been off gluten 8 months. It was about 90% clear when hey stopped. I finally took him to a homeopathic MD who did a simple blood test and put the whole thing together. Although if hey goes on a antibiotic for anything, hey gets it back..tjen its yeast. Its very tricky. Please call when its a good time. Good luck!
