Hilo,
Welcome to Healing well! Sorry you're having so much trouble. Does your doc think this is spasticity from the MS? It sounds like it to me. Baclofen works wonders for spasticity and spasms in the legs. It's pretty easy to get used to, has very few side effects. As for the nerve type pain, maybe lyrica would help. Ask your doc about these drugs. Take care and let us know how it goes!
