osteoarthritis
"Had my first injection 18 months ago 1st injection of series was no pain, 2nd of series extreme pain, swelling, stiffness, 3rd injection no pain. I had no real knee pain for 18 months remained active with Pilates, hiking, walking, circuit training. Pain started again in June 2017, started injections again in September, 1st injection no pain, next day no swelling but few twinges.   I hope I get another 18 months or more. Had surgery 2 years ago,  Knee remains stable right now, goal is to avoid any surgery for now on."
