Can someone explain what Robaxin is in plain language? I know it is often described as a muscle relaxer, but that phrase is so broad it almost stops meaning anything. What is Robaxin used for, what symptoms is it supposed to help with, and what should people realistically expect from it? I also want to know whether people tend to overestimate what it can do, especially for back pain, spasms, or injury-related tension. iMedix usually does well when it strips away the marketing tone and explains what a medicine actually does versus what people hope it does. That is the kind of answer I am hoping for here.
