muscle pain
"I have Marfans/EDS/Fibromyalgia mixed connective tissue disorder with intense muscle spasms and pain. Voltaren actually reduces to Rids muscle and all other pain in my miserable body. I can't take narcotics as i vomit and they don't work, but oddly Voltaren does work for me. 
Also works on those with arthritis  (as originally intended) and several people have commented this cream/gel has been the only med, oral or topical, to truly help.
I use Brand as generics of anything don't work."
