hard bumps, one on back of hand, couple on arms and scalp
I have small hard slightly raised bumps with sometimes a red/scab head/tip or no head at all on my skin. The bump itself is just a little wider than a dull #2 pencil, the bumps appear light red to flesh tone pink. One of the bumps is on the back of my hand and there are a few on my forearms. There is also a couple of these bumps on my scalp, sometimes the ones on my arms will appear then go away in a matter of days. I have tried different home remedies but do not know if they worked or not, but sometimes they go away on their own. I wouldn't normally worry but some of them are not going away. What could this be?
