i'm taking a stab in the dark here (no pun intended). i was diagnosed with a fractured coccyx two years ago. no x-rays were taken. this was my doctor making an educated guess. he set me up for physical therapy, which i went through for a few weeks, and the pain subsided within that amount of time. this is the part i cannot explain: i am a drummer and i have never had a problem with stamina or flexibility in either of my legs. i happen to be a drummer that plays Heavy Metal, so it's an extreme style of playing. however, after my accident (i fell down a flight of stairs and landed on my left buttock) i have lost the ability to fully control my left leg. it cannot keep up with my right leg. when i play my bass drum pedal with my left side, my left foot starts to turn inward to where my left heel is pointed toward my right foot. my left leg also cramps and tightens up to the point of it being frozen and immobile. there is no unbearable pain involved though. just the pain that is associated with cramping. i can't figure this out. the only answer that i can come up with is that i'm experiencing nerve damage of some sort. other than sitting playing my drums, i never experience any trouble with my left leg whatsoever. this is destroying me. can someone please help.
