does anyone have any idea what these might be, they are not itchy, but when i get them they swell up and don't go away for weeks, and they leave a red scar, it's not like a rash but more singular bumps that form in an isolated area on both of my hips. there are also white bumps that do not hurt but if squeezed hard enough they will have a white kinda zit like squiggly line of stuff that is discharged. like a whitehead but it's not fluid it's more solid.... this problem has been going on for a couple of years and my doctor (not a skin specialist) said it's not herpes but it may never be resolved because of my belt line.. but it's embarrassing and i don't think she is right about it not being resolved.
