osteoarthritis
"I have arthritis in both knees. One is severe bone on bone the other is moderate. So they started injections in my left knee first as the right one wasn't bothering me too much as the cortizone shots was still slightly effective. So got two shots not too bad as far as pain. Go get the 3rd one and the doctor didn't take her time like before to find just the right spot and she injected me. As soon as she started putting the fluid into my knee I felt a burning liquid feeling going from the injection site (the outside of my knee to the inside of my knee) It didn't stop there. It felt as she put more in like my knee was going to explode out the side. I was not expecting that. I just held my breath and when she was done I said. Wow that hurt. Why"
