My mom is having severe neck pain. She's in her mid-thirties and she can barely move her head. She's tried Ibuprofen and a few other OTC (Over the counter) pain relievers, but it hasn't worked. She's been in pain for the last two days and it seems to be getting worse. She has an icepack placed on her neck and says she can feel the stiffness in the base of her skull. Will this help her, or at lease make her sleep without being in pain??
