How To Treat Nerve Damage And Heaviness In My Body?

I have nerve damage and basically it's been under control. After arriving from a cruise (thought it was just sea leg) I started falling. After about three days later I realized the symptoms were that of the nerve damage. I'm currently taking folic acid and vitamin b. Why am I still very heavy in my body; I can barely walk. My breathing has gotten better however. Only been on medication for four days now. Also, talking another drug for glouten (I think it was).
