Hello, I ve had mild muscle spasms in my lower back which were helped quite a bit by physical therapy. Now I m having less pain in the back, but I wake up with pain in my legs (shin and calves). They go away after a few hours and with ibuprofen and Baclofen, but is there something I could do other than take these meds? I have fibromyalgia and sleep on a 3 memory foam topper. Could I be lacking a certain vitamin? I do take a women s over 50 daily multivitamin.
