I just spoke with a chiropractor in my town yesterday. He has been doing stem cell injections (from umbilical chords from healthy births). The injections are not cheap. $5000 each (of course insurance won’t cover it. No money there for big pharma) but he says where back surgery has about a 40% success rate this has about 80%. I personally know someone whose parent in their late 70s maybe early 80s had it a few weeks ago and the improvement is stunning. He treats backs, hips, knees, shoulders etc with this. Side note. He also does an oxygenated blood treatment that has amazing results on a lot of different autoimmune diseases and made a dramatic difference for a patient who was legally blind after a histoplasmosis infection. These are $150 each and a course I’d usually about 10 treatments.
