i had to pin myself for the first time in years. also i didnt have a mirror so it was a bad spot. about 4in left of ideal spot on left glute. weird enough if felt like the nicest one ive ever had. about a day and a half latter it begun to hurt if touched and i have a bump on my butt but not really on the spot i pinned. lil bit closer to where it should have been. bump has been there for about 4 days thoughts?
