Hello. I have been having a recurrence of bumps on my back, buttocks, and my legs (sides and back of thighs) for some time now. Occasionally I ll have pus-filled bumps like large pimples pop up in these areas, while my upper back has small red bumps and itchy areas constantly flaring up. The pus is sometimes clear, then turning to blood, while other times an amount of milky white discharge or even blackheads will pop out. Please help me find a solution to this problem! It s often embarrassing to take my shirt off in public, or even with my significant other.
