Acupuncture fixed my shoulder pain. Misc doctors GTFIH

I injured my shoulder last October while doing some tradie work in my yard and had some kind of rotator cuff problem. Did a whole bunch of bands and light dumbbell work since but didn't really make much difference, then in desperation had some acupuncture and now after 3 20 minute sessions the pain and mobility is MUCH better.

Wtf brahs I thought this was just nonsense hippy chit. How can it actually have worked?
