[QUOTE=spacehopper;5103841]I swear by thermacare heatwraps. They are great as they stay warm on my lower back for hours. I don't think they advise you to sleep in them, but I do and they help me sleep all night, rather than waking in pain. They are expensive though, but I feel they're worth it. You can get 4 for £5 at costco, although as you're spelling mummy with an o, I assume you're from the US!
Haha, yes! But we have a Costco! I go to a place called SAMs club. I heat my lower back, although, my pain is in my leg, lower right leg, in the back. I just hate this!!! If ice my back, my leg feels better. Go figure!!! Hang in there, and thanks for your reply!
