Joint effusion of the knee is the most common symptom of osteoarthritis. There may be a formation of bunion at the toes which makes them red and swollen. A bunion is an abnormal, bony bump formed on the joint at the base of the big toe but it can be due to other causes too.
My elbow seems to be full of fluid; it's swelling like crazy. I don't know what's causing it or how to get it to go away. What should I do? From the description of your symptoms it sounds like you may have a joint effusion, which is exactly as you describe: fluid that goes to the joint. The question in this kind of situation is what is causing the effusion. In order to figure this out, the best thing for you to do will be to see your primary care physician right away for an evaluation.
