Injured

I've been out of commission the last few days with a really crappy muscle spasm thing. I'm not sure exactly what I did-- but for the last few days, my left shoulder & up through my neck, and left side of my face will all of a sudden develop searing pain... which will last a while, and then go away. I've been seeing the chiropractor at least daily. Yesterday, I saw the primary doctor (felt slightly cool to acknowledge I'm training for a triathlon). Diagnosis: Muscle Spasms. Treatment: Muscle Relaxers, which are great, but I can't stop sleeping.
