Hi Doctor, I have these small bumps on and sides my stomach, and some on my thighs and buttocks,not itch and no pain, flesh colored, usually one bump appeares and gets little bigger and soon surrounds by small bumps and forms a cluster or they form like a straight dotted line and leaves dark acne like bump and in small fleshy patches, I thought that it might be KP but am not sure anymore, please help me. Thank you.
