My GP has recently confirmed that the pain and swelling in my fingers and wrist is arthritis. He gave me painkillers and anti-inflammatories, which cause the most awful stomach upset. He told me to take the tablets when I needed them, and that was about all he said. Recently, my knee has become really painful and keeps swelling up. Should I go back to my GP-is it possible that I have arthritis in my knee? I felt he was really unhelpful, and didnt give me any information about the condition, or advice on anything else I can do.
