As someone who suffers from occasional back spasms can attest, you can't do ANYTHING when they are in high gear. I'd rather function with a broken bone. That being said, I don't think you can just say that someone will be out for three weeks with back spasms......it should be day to day because you can't really predict when you'll get better. Am I wrong? Are my doctors? Someone tell me if I have this wrong, but I'm really wondering if maybe something else is wrong with him.
