Review (3/5): May have helped
I used this consistently for over a month, three to four times a day. My forearm hurts a bit less than it did when I started using the cream. Whether the DMSO is responsible there's no way to know. If so the effect is small and slow. There was no immediate lessening in pain. I also got an ergonomic keyboard, which may be the cause of the lower pain level, or it may have been the multiple daily massages that I applied to the sore areas when I rubbed in the DMSO cream.
