I have just found a lump approx 2 inches above my tailbone, it is a little to the left. It is hard, not perfectly round and doesn't move. My husband thinks I am crazy to be worried since it is where it is, in the muscle area (he is no doctor) he just thinks everyone's bottom has this?!
It is perhaps a 1/2 inch in size (??) it is hard to tell because I can not feel the entire edge of it.
No pain. I am scared to death!!
