I always clean my skin with colloidal silver before dabbing the DMSO on since 
it can carry things in through the skin.  I've never had any body odor from 
using it (and I keep asking my husband if I do).  My DMSO is 60%.  
https://jacoblab.com/OrderDMSODusa60.html     I know you don't have to spend 
that much for DMSO, but I love the ease of using this kind and have never had 
any irritation or problem with it.  One bottle will last me years. 

 Currently I'm using it on my knee for tendonitis.  I have a partial knee 
replacement and the orthopaedic surgeon ok'd the DMSO in the daytime and an 
NSAID patch at night.  My previous orthopaedic surgeon had approved DMSO use 
also, and that time it cleared up a tendon pain in a couple days after weeks of 
it hurting.
