A member asked:

A few months ago i noticed a marble-sized, hard lump on my tailbone. there's no pain, but i keep worrying about it. could it be part of my tailbone?

A doctor has provided 1 answer

A pilonidal cyst : A pilonidal cyst occurs at the bottom of the tailbone (coccyx) and can become infected and filled with pus. Get it checked.
