Traditional medicine, Chinese or otherwise, is bullshit. If some tincture happens to have some active ingredient that actual does something, then that ingredient has almost certainly been studied by actual scientists, purified, dosed, and available as a safe (relatively) form at your local pharmacy.
Acupuncture and cupping in particular are no better than placebo at relieving pain. Any temporary relief your partner receives from them is no better than a sugar pill that they are convinced will help them, or no better than the pain relief of a massage. What does everyone do when they bang their knee or elbow on something hard? We rub it. Why? Because rubbing stimulates the surrounding nerves and that extra stimulation helps to drown out and dull the sharp pain…temporarily. Any pain relief from acupuncture and cupping is no different and isn’t permanent. Your partner would be better off going to a licensed physical therapist, with an actual doctorate degree and deep understanding of anatomy. They will not only know techniques to temporarily relieve the pain, but also will be able to provide a custom exercise plan to strengthen the affected area to help prevent repeat injury.
Also a lot of non-scientific “medicine” is extremely dangerous. I know people have had serious injuries from acupuncture, but chiropractors are the worse. Don’t let anyone you care about go to a chiropractor. At best you become a repeat customer and waste a lot of money on a glorified massage from someone pretending to be a doctor, and at worst you end up a paraplegic or dead.
There may be some chiropractors that know it is a sham and therefore don’t do some of the more dangerous maneuvers out of fear of hurting someone and getting sued. But I’m not taking those risks and the entire practice is pseudoscience nonsense.
