Red, itchy bumps on my lower legs after hair removal, will it go away? Do I need to see a doctor? (photo)

Every so often, we do see an itchy bumpy rash following laser hair removal. This is usually because of irritation of the hair follicles in the treated area, and this can be easily treated with a mild cortisone preparation. I suggest contacting your Dr. for a topical solution. Best, Dr. Emer

From the pictures you provided it appears you are having an allergic reaction to some sort of topical cream or gel used for your treatment.  I would reach out to the provider immediately and have them guide you on a cortisone cream of some sort.

From your photo, it looks like you are having an allergic reaction to something applied during your treatment.  Did you have a topical anesthetic or laser gel applied during your session?  I would recommend seeing a dermatologist for medication.  Most likely a prescription strength topical cortisone cream or foam will be helpful in eliminating the rash. Try to find out what products were used to hopefully prevent this from recurring during your next treatment.
