I know this is a subject that has appeared before but it seems to me that no one has ever come up with a specific diagnosis/treatment for the spontaneous bumps that appear and cause so much discomfort. Have been seen by dermatologist who biopsied same - report states insect bites - these are definitely not insect bites. Wondering if anyone else has managed to get a definitive diagnosis related to this problem. Lesions occur at all times of the year and last sometimes for months - they are extremely itchy and cause much discomfort. Have tried course of steroids which worked for a short time and then problem returned - antihistamines are ineffective as are topical steroids which provide momentary relief. Would appreciate any input as to any effective treatments or duration of problem.
