The volteran has taken the edge off for me, but that’s about it.Am suddenly dealing with pain over my left hand fretted thumb joint. I’m all over the place with my instruments and I just play for fun. On a typical evening, I start with a 30” fretless and often wind up with a 35” fretless. My pain began when I went back to one of my fretted basses Long story short- I typed in- Voltaren” and wound up here after changing my thumbing behind the neck. Has anyone here ever gotten relief using Voltaren?
