Hi Susanne, Sorry to hear about your fall. A hard knock to the tailbone can take sometime to recover from. I know this from experience. I slipped and fell on my back in mud many years ago and was a sight for sore eyes. Witnessed by a passer-by, who had to help me get back up again. I remember laughing at first, also. Hoping that you see some relief soon! However, if the stiffness and pain persists it probably would not hurt to have yourself checked out. Wishing you a speedy recovery. CeCe.
