Thanks for the replies. I guess I should probably go get it check by a dr. It is just so easy though to blame every little ache and pain on my MS. I think I'm truly scared of having yet another thing wrong with me. MS is enough.

I was using heat, but it only seemed to get worse. I have been taking an Aleve before bed so I could sleep, but it didn't help it last night. I may try icing it today and make an appt with the dr.

Thanks again
