osteoarthritis
"The first time my doctor suggested Voltaren cream. I have osteo in both knees, right ankle and my spine. After several tubes and no reduction of pain or swelling my doctor suggested Pennsaid . The difference was like day and night. Not only did it reduce the pain but the swelling in my ankle was also reduced. When I investigated both products I was shocked to find that only Pennsaid contains a delivery agent DMSO that Voltaren does not . So it seems the DMSO delivers directly into the joint while the Voltaren only stays on the skin. Bottom line I will never spend my money on anything else going forward ....Pennsaid works for me."
