[|Human|] Hi, My 22 yo son has had a very itchy rash all over his body for quite a while. He was allergy tested, and went to a dermatologist. All have tried many things, and he changed his soap, shampoo and detergent. Still has rash. He has crohns, so he takes the following: entocort, pentasa, canasa suppositories, along with Adderall for his ADD. Any thoughts on what can cause this rash. He says sunlight helps it some. Thank you for any insight you may have. We re running out of ideas!
[|AI|]  Hi, The possibility of Allergic contact dermatitis is ruled out as the rash persists even after changing cosmetics. The rash could be a side effect of one of the medications that you have been using. Another condition which improves with sunlight is atomic dermatitis. Final diagnosis could only be made by ruling out other conditions after proper clinical examination. For that purpose, I request you to consult your Dermatologist. Hope I have answered your query. Let me know if I can assist you further.
