I was induced to have my second child. I had an epidural that was misplaced and caused nerve damage at L3/L4. It caused me to fall quite a bit due to loss of function of part of my left leg. This caused misalignment of coccyx repeatedly which caused excessive pain with sitting, pain with gluteal contraction/use, and problems with going to the bathroom.
Through physical therapy with Jennifer DeLorenzo (see Doctors and specialists in the USA, Virginia) my coccyx pain has now resolved, going to the bathroom is less painful and easier, and I fall less.
