osteoarthritis
"1st injection= mild swelling then relief. Injection 2 = intense swelling and pain. Synovitis. Had to get a steroid shot. Injection 3= they felt maybe the 2nd injection was in the wrong place and wanted to try again I did. Worse swelling and pain. It is not a suck it up buttercup thing. I am an ironman and have had surgeries. This is abnormal and swelling to the degree of not being able to bend my knee to 90 degrees. Nor straighten. It is painful and tight.   Bad reaction not good and not normal.  Now I will be at the Doc Monday 72 hrs post injection b/c I am so swollen I can hardly function.  He will draw fluid off and give me a steroid injection. This is awful anyway - too common."
