I thought I had just better post a warning about the usage of DMSO.  As you 
know, I put the gel on husbands knee and it worked but produced this rash.  
Well, two weeks later he still has the rash and I looked it up in Widepedia.  
It seems that quite a lot of damage can be caused by solvents and it seems that 
this has happened in this case.  I realize that I shouldn't have used it neat, 
but as there are no instructions on the container, this is understandable.  It 
actually says *not* to get it on the skin but because I knew that people did 
use it I ignored this.  I'm just posting this to say that if anyone is 
recommending this product to anyone (including for use with animals) it has to 
be very clear how to use it. I am desperately hoping that this will reverse in 
time, but at the moment, he is in massive discomfort and the use of 
anti-histamines does not seem to be having much effect.  We are off to the 
doctors again tomorrow to own up to what we used.  No doubt I'll be getting a 
well deserved lecture.  Dee
