In January of 2020 I had my second knee replacement . The left leg was done and 6 weeks later I had severe pain at the back and left of my ankle. Several months later after prednesone and pt my knee surgeon gave me a corizone shot in the ankle. two days later the pain went away. Then in February of 2021 it came back. went to get cortizone shot and they said they can't do them anymore they are to dangerous. went to an ankle specialist and he said the same thing. Starting pt for gentle stretches and I am in an aircast boot. That is doing a terrible number on both my knee replacements. Any suggestions what I can do for my knees since they are stiff and painful.
