What is the best medicine to help with tight, sore, hurting muscles? My back, waist, and legs have been hurting now constantly for almost 2 weeks. Yesterday and today have been the worst days, and it seems to get worse as time goes on. I hurt and I'm sore all over. I've tried the pain med Tramadol, but it seems to not help anymore. My mom suggested Folic Acid to help with the soreness.

What is there that can help me?
