Ok I'm really feeling ashamed for posting this here but I can't cope any longer without asking. For a few years I've had these spots/boils on my inner thighs (sometimes in my armpits) They're puss-filled and can last anything up to about 3 months. When they go they leave purple scars which look horrible. I keep them clean, but they don't tend to go away. The skin is also a bit discolored down there too. What's wrong with me?
