Good stuff
Bought this for my sister who suffers shoulder pain and at 85 doesn't want to brave another surgery to replace her shoulder joint.  It gives her some relief; how much relief depends on a variety of factors, especially the weather.  DMSO was an ingredient her nurse practitioner suggested.  We bought this when insurance wouldn't pay for a prescription product after considering horse liniment at the feed store that also contains DMSO, the active ingredient. This is probably less likely to cause irritation.
