So I've had these bumps for a few months now. They are small pimple like and very itchy. They seem to itch more when I get in the shower and the hot water hits them. Like pimples, they will flare up at random with several and then go away. It seems to mostly trace my jaw line to just behind my ear lobes. I've tried many different face washes thinking it was acne or pimples but it doesn't seem to help. Any clue what this might be?
