Yes. I have had it myself for back pain caused by muscle issues and sorted out a horse's back muscle problems with acupuncture. The vet who did it also does chiropractic and told me about a horse with sarcoids which he had improved with acupuncture.
I had it performed on my girl when she had facial paralysis. She had 1 session a week for 8 weeks then another 3 every month. Her face went from a droopy mouth, non moving ear and non blinking eye to everything 95% back to normal. It should have healed anyway but given she was 19 at the time I think progress would have been slower and it was all about getting the nerves to regenerate quickly or they may be lost forever. For me it was a godsend. I got my girl back!! Try it!
