About two to three months ago i started to get these individual tender white head pimple like bump on my legs mainly and butt. At first i thought it was an insect bite, bed bug bite, or ingrown hair bump. They are not. Its just a random tender hard when i touch type of bump, with no cluster of other bumps around it. It apears random and individual throughout the months. I notice it because it like a small sharp pain that lasts just secs. Its hard, dime to quarter size and has a white looking head. When i pop it, its not like a pimple with pus, its more of a clear liquid that comes out, and the white head is gone. Then the bump goes away in a couple of days. And another would appear two to three wks from the pevious bump. What could this be? All the bump like diagnosis ive seen are clusters and not individual
