People above mention valium. If the muscle spasms are caused by tense muscles due to anxiety or work and one is not relaxing than valium works. (gives me nightmares after 3 nights in a row.)
Also the masseuse thing - that is superficial. A MYOFASCIAL DEEP TISSUE RELEASE - there is a section here about it. I think they call it MFR (Myo Fascial Release). They will work you over but good! None of those woosy massagers usually do it or do it deep enough. It is PAINFUL. But it works. I go on a regular schedule. Aging is a bitch! And the topicals are part of my arsenal. make sure you get prescription strength, not over-the-counter versions.
