ibromyalgia
"I have had fibro and chronic fatigue for years.  I used to take Skelaxin occasionally.  When I developed degerative bone disease and increasing arthritis, I decided to take it regularly and see what happened.  Over a period of a few months, I have found that my pain has reduced significantly.  It is one of those drugs that seems to work better when taken regularly as opposed to for an acute attack.  The down side is that it is expensive, even in generic form."
