hello, ok well i have this acne problem. My GP doesnt even know what it is. When i get a pimple on my face, it hurts very much, but it does not break out. After a few days, the pimple hardens and eventually starts turning dark in color. When a few months go by, the bump on my face starts looking like a bruise, and does swallow up time to time. When it does break out after a few months, alot of dark, thick blood comes out. I'm just wondering what this might be as it seems very unusual to me that i have such bad acne at the age of 16. Please reply, your thoughts would be much appreciated.
