Can work in limited cases - up to you find out which.
By nature, I'm not a believer in surface topicals that relieve pain.  However, I have to acknowledge that it seems to work on small injuries around the thumb joints cause by piano practice.  These injuries, probably some kind of ligament micro-tears, are painful throughout the day.  In this particular case, this product seems to give 100% pain relief.  Weird but true as I have repeated the experiment more than once.<br /><br />I have tried it on similar injuries around the underside of the elbow (again from piano practice) that resulted in less benefit but still some relief.<br /><br />My spouse is a believer in this stuff and as you can imagine, realizes much better results.<br /><br />Well we bought a large bottle and its nice to have around.
