You have done rheumatoid factor test but you may also need to do uric acid levels in blood because it can be related to gout or pseudogout and also a x-ray of the knee or better an MRI to see the conditions of the joint ind of fluid is accumulated there.
Use anti-inflammatory drugs such Advil or naproxen for pain and swelling. Use cold compresses on it to relieve swelling and redness. Keep the knee at rest and elevated.
