DMSO
Works great.  A friend of mine's family raised race horses and she told me they used to get it for the horses and used it for their own aches and pains.  She said her husband and father only used this for all sorts of pain.  So I decided to try it when I saw if here on Amazon.  Actually, I was purchasing something else when i saw it and decided to order it also.  It is great.  I don't have many aches and pains but I twisted my knee the other day and the pain was terrible.  In a couple of day, it was gone.  I used it in the morning and evening only.
