I was in a car wreck at 14 and since then have a subluxation in it if i move it wrong and i haven’t had full use of it . I’m 70. I went to chiropractic for 40 years and also took physical therapy for my arm and it helps but I don’t get any rotation or movement in it my whole life. David started massage with me about a year ago and I can now lift my arm straight up that I’ve never been able to do and it hasn’t popped out one time this year. This is one of the few things he has improved on me. Another being brain fog and dizzy spells from problems in my neck but he has cleared that up as well. I can’t say enough about this healer.
