Hello. I am a 16 year old female. For about two years, I've had this recurring red rash around my mouth that is very dry and itchy. I have been to numerous doctors, who have diagnosed it as contact dermatitis or eczema. I have gone through patch testing (all negative results) and have been on various steroid creams, which only help temporarily. I have also been on oral antibiotics, which helped for a month, only to return full blown. The only thing left I can think of is possible food allergy? Any comments and help is greatly appreciated!
