Something so silly that caused so much pain

So two weeks ago I was leaning out of my office chair to plug in the iron.  Next thing I knew I was on my back on the floor.  Seems harmless enough and yet 30 minutes later I hurt.  After 3 visits to the chiropractor, and now a visit to my PCM who gave me pain killers and muscle relaxers I still HURT.  Note: do not lean out of an office chair!
