I have raised hair follicles on the back of my forearm on the same side as my elbow! I am african american and they are little black raised bumps, some bigger than others. Could it maybe not be hair follicles and I maybe need to scrub my arm more when I shower? I have tried scrubbing harder and it just turns red, they are very ugly and make me look dirty, they are not flat, I can actually feel them if I run my hands across, any ideas of what these could be?
