Can't Stop Injuring Myself

Monday night, Jerod goes to play racquetball for the first time in... well... too long.
Monday night, Jerod injures his back.
Tuesday morning, Jerod goes to Student Health and is told he has a muscle spasm in his back.
Tuesday, Jerod takes prescribed muscle relaxers and goes to classes (there's a good idea).
Wednesday, Jerod feels a little better, but his lower back still intermittently tightens and loosens up.

That is all.
