I had a back and leg problem and for this visited a Traditional Chinese Medicine doctor in Kunming. He does acupuncture, but combines it with chiropractic work on the spine. It helps for me. Also been to a chiropractor back at home in Europe and basically the treatment is comparable, except for the needles of course. I guess you can go to any TCM doctor in Lijiang. The one I’m visiting in Kunming has this address; 云南省-昆明市-五华区-茭菱路566号(富滇银行旁). Good luck.

There used to be a gym + pool at Beichen, called Kalenyi Swimming Fitness. Closed a few months ago due to COVID obviously. Went there today as many gyms re-opening, but they’re renovation the whole building now and the whole gym seems to have disappeared..
