Father in law OA both knees
I've joined here on behalf of my father in law who doesn't use the Internet. He has severe arthritis in both knees but also has chronic kidney disease so cannot even use voltarol gel on them as this affects his kidney function. He does daily exercises which the physio showed him and he tries to keep as mobile as possible but he is often in really severe pain and can only take paracetamol.
Can anyone suggest anything that might help relieve his pain?
