I had one in my hip last year for bursitis. I thought I was going to need a hip replacement. Cortisone shot knocked out the pain entirely. I’ve had them in my elbows which also worked. No luck with my thumbs, though. I’d say go for it.
That's what Sandy Koufax used to get to keep pitching.
I had hip bursitis this past year....chiropracter fixed me in 3 very short sessions of the Graston technique...no drugs, no shots.
