Michelle,  Your mother actually has tried acupuncture and it worked for me! 

Remember my torn ACL and Medial Meniscus injury?  Well not only did I have physical therapy on the knee but I also went to a woo woo doctor aka chiropractor.  Yes, she is legit and treats sports injuries for the runners in dad's group. She did the most for my leg.  She did some kind of massage but she also did acupuncture.  Oh my gosh did that ever work wonders on that knee.  She was the one who saved me from having to have surgery.  The acupuncture got the swelling down.  My knee weeped trapped fluid out of every needle site and the Baker's cyst behind the knee disappeared completely.  That cyst is trapped fluid and it got rid of it.  

I am a believer in acupuncture!
