Dear Marianne: Oh do I get muscle spasms, and this low back ache, that is killing me. I usually have the muscle spasms all over, neck, back, arms, hands. Not so much my feet and legs. The low back ache starts then feels like someone have kicked me. I can't bend or stand up or get up, etc. I don't know what to do with them, but if you find out please let me know? Thank you Gina 47/7mos
