Amazing!
So my dad suffers from chronic gout.  Each time he gets rid of it in 1 area, another starts hurting.  One day he was talking about DMSO and that if available in the states,  it would be amazing.  So to Amazon I went!  After a short search,  I stumbled upon this product.  It arrived 2 days later and my dads knee pain disappeared!  I'm buying for a friend who also had chronic knee pain.
