I had laser treatment last week for cherry angiomas on my stomach, back, and back of neck. It has been 7 days since the txt. I have developed an uncontrollable, itch, red, patchy rash that is spreading across my trunk and back. Hydrocortisone 1 and 2% did nothing. Benedryl spray doing nothing and Betamethasone Dipropionate presription cream doing nothing. Pleeease..there must be something. ??? I m miserable.
