I’ve had three doctors and two physical therapists tell me to keep running. That being said, I’ve been running for years, so it isn’t new for me. I’ve reduced it a bit to faster walking, but I think it’s the reason my hips have stayed stable. Doesn’t do too much for spine, I don’t think. If I was your age, I think I would investigate HRT, but I’d be very careful to find a doc who truly specializes in that area. Probably just as difficult as finding a good one who specializes in osteoporosis!
