Well that was done. She had a full back patch test to about 50 allergens (not sure exactly what they were). Nonethless she had no severe allergies to any of them. The dermatologist told her that it has to be something intrinsic to me and subsequently told her that there is little that could be done aside from removing the allergen (aka me). From my understanding though, one cannot be allergic to saliva, just to components within it. I suspect something in the water at my place which I drink and shower in.
Hello,
It is very strange and unfortunate that she is allergic to your body secretions. It may be that she is allergic to the cosmetics, soaps, detergents etc you use. To confirm the diagnosis, she needs to get skin allergy tests done.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
