DH...or not? in Dermatitis Herpetiformis Posted May 29, 2017 · Report to Admin Thank you for your replies, everyone! It was very helpful. I don't think I am comfortable with passing the whole gluten introduction diet again and getting that rash. Or, even getting the rash on my face flared up again. It actually might be a good thing I got 'glutened' at that bd party so I could finally make connection with all the symptoms. As I thought back about my 'allergy' rashes I start wondering if it could be related to gluten all those years but no one even suspected. For example, at some point I started getting itchy rash around my knees, spreading down to ankles (front of the legs) in summer. The dermatologist and GP said it is 'sun allergy'. The usual allergic treatments helped for the itch and the patchy scales slowly healed but it flared up on the same place during the summer multiple times. The strange thing is that it never flared up when I went hiking, or walking in the sun in the city (I have extremely low vit D levels and I need to supplement, so it was no-no to stay completely covered no matter the rash...I needed my natural vit D). The rash only appeared after beach visits. At some point I started washing and drying my skin with a towel every time I went out from the sea, the rash still appeared but I was able to control it so it showed up on day 4-5 when vacation was almost over. Then, last summer after I was completely gluten and dairy free for approximately 9-10 months, and I was annoyed of washing my skin each and every time and getting those weird looks on the beach, I stopped doing it. I was prepared with medicine and creams for that rash but guess what - my 'sun allergy' was mysteriously gone. Not a single blister, not a patch of itchy skin, nothing. Another 'allergy' case of mine is that I found from my own bad experience I got very bad rash from red dyes (in food or cosmetics). If it is food it shows on my face, if it is cosmetics (soaps, perfumes)...whenever I applied it. I am now reading that people with dh should stay away from red dyes. Mere coincidence? I don't know, I am more and more suspicious I could have this DH thing going on for years, if that is DH. I am just annoyed that all the dermatologists I went to during all those years never made connection. No one even suspected. It was the usual path - cortisone creams, pills, etc. At some point cortisone creams were no longer working so they started prescribing some mixtures made in the pharmacy specifically for me with sulfur. That worked like a charm but I couldn't walk around all covered in white cream looking like a mummy (long sleeves in summer here where I live and summer = 35-38 C, is not fun). Then, I tried homeopathy....it worked like a charm but of course those rashes kept appearing and disappearing, I was only able to control the itchy skin so I don't scratch, scratch, scratch...looong, long journey! Sorry about my rant...and, one more time thank you everyone who found the time to reply and share your opinion! Much appreciated!
