pain
"I have Fibromyalgia and it does help.  Because fibromyalgia is a different sort of beast it helps some but does not knock it out.  However, it reduces pain very quickly.  Using more at one time or more frequently does not bring the pain down any more.  It did not work that much on my wrists and hands where carpel tunnel is "suspected" but they are not certain what it is.  Some other pain on hand and arm were helped but not overly so."
