Tailbone of Doom

Went to the doctor because my tailbone has been hurting for months now, whenever I sit too long.  Xrays show...nothing.  Inspection shows...nothing.  I hate it when you don't get any result.  My tailbone just hurts.  It's a mystery. Could be ligaments or something... I wish I had never gone and waisted the money.  Now I just have to take anti-inflammatories and sit on a ridiculous pillow and hope it goes away.
