muscle spasm
"Ruptured lower disc. Been using for two days; take 500mg before going to bed. Previously could not stand or walk for more than two minutes. This has absolutely helped me walk and stand longer. No side effects. I don't like taking any drugs; so, I may try at 250mg. With my positive results and limited use so far and not being a narcotic, I'll be recommending this to my mother-in-law."
