I have been getting raises areas of flesh on my inner/outer thighs, and do not know what they are. They are somewhat painful to the touch, and though they are raised and easily graspable, the skin is simply too thick to pop. They are usually about the size of a dime. I've tried needles, but I rarely get any pus. The raised area becomes purplish, and eventually it diminishes and goes away whether I do anything to it or not. Is this acne? Am I missing something? Do I need to see my doctor, or just shower a bit more thoroughly?
