I note your history clinical findings as per your reports. Dermatology is a visual field as such, it will be much appreciated if you could upload some photographs on this site using the upload data feature on the right side of your page. I suggest stopping the steroids antihistamines for 2 weeks then going in for a skin biopsy to get a definitive diagnosis. Please ensure the histopathology is cross-checked with an immunofluorescence study in addition for a better picture. Also, at the same time 2 was after quiescence you may want to do a patch test to check for various allergens. Wish you a clear skin soon. Cheers! Chat Doctor.
