Aw, Bethie, those nasty little buggers do hurt! Mine are real bad and if I didn't have my Zanaflex in flexible doses, I probably wouldn't sleep at all.
I agree, you really should call it in, even if they just give you a prescription for more or something else, you'll be doing something about it.
Not to make it seem worse, but my friend, mine have not gone completely away for years now.
Stretching helps, but only a little. The drugs are the best defense I've been able to find so far.
I actually know how you feel.
