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 immunoflorescence study in addition for a better picture.
Also at the same time (2 wks after quiescence) you may want to do a patch test
to check for various allergens.
Wish you a clear skin soon. Cheers!
