I get these red soft bumps with dark purple centers on my inner thigh sometimes. They don t really hurt that bad, and they never have a head like a pimple. The only real way I can get them to go away is to take a sterile exacto knife (steralized with rubbing alcohol and fire) and lance it. At this point a thick blood-puss mixture is released. After I do this to the blemish, it usually goes away within a few days. Are these anything to really worry about, or are they just boils?
