muscle spasm
"Methocarbamol was originally prescribed to me for a misdiagnosed muscle spasm. I was later diagnosed with multilevel disc protrusions of the L1 and L5 discs. The L1 protrusion was pressing against the sciatic nerves and causing extreme pain in the lower back, hip and upper leg areas, hence the condition sciatica. Methocarbamol has no effect on the pain. Tramadol is more effective, with relatively no side effects."
