A month ago both knees were injected with cortisone. My knees were in a bad way prior but now the bursa is swollen around the knee, pain below the knee, and intermittent sharp pain inside the knee when walking. I was using a brace and cane prior to the shots and now I use 2 brace, 2 canes, and/walker and can barely get around. The skin on the inside of the left knee is very sensitive to the touch now as well.
