muscle spasm
"Suffer back pain and sciatica from pinched nerve caused by herniated lumbar discs. Prescribed Soma by new orthopedic doctor for pain. Does not work any better for my pain than ibuprofen and comes with a multitude of side effects. I am discontinuing use after one week due to headache, dizziness, nausea and insomnia. I don't know if my emotional reaction is due to the drug or the 3 months of chronic pain and recent lack of sleep, but it is making me irritable and angry."
