hello, i few days ago i noticed that one side of my butt cheek was sore, i didn't really pay much attention to it though, but now 5 days later it hurts a lot, its a hard lump inside my butt cheek, but from the out side its very red and about a dollar size, its not squishy, so i'm guessing it doesn't have liquid inside, i've tried to drain it but nothing came out. it hurts to walk, to sit, to bend over, to lay down, and basically anything else that involves my legs or butt. do you have any idea what it might be and what the best treatment is? Thanks (:
