I Fell Backwards Onto My Cement Front Sidewalk At Home.

I fell backwards onto my cement front sidewalk at home. I hit my tailbone area and now I have one of the bones in my tailbone area is sore. It doesn't bother me to do most things but I do notice that when I have been sitting on my couch that one bone is noticeably sore. It's not maybe just one bone in that area is hurting sometimes, not all the time.
