Recent diagnosis of osteoarthritis


I had 2 falls involving my knee within 6 months. The most recent one involved me getting an xray and a ct scan. And being on sick for 3 months. The results showed I had osteoarthritis. I was told to take Paracetamol and ibrophen. These don't work. The pain has got worse in the last month. Not only my knee but sharp stabbing pains in the back of my ankle which come and go. The pain is constant under my knee and I struggle to walk. Could you give me some advice on what I can do
