Patient: I have what I think is an absess on right knee, outside of the knee cap. It’s approximately 2″ by 1″, warm to the touch, and very sore to the point that I can’t kneel down and put any wieght on it. I can feel the fluid inside the ” POUCH “. should I go to the hospital and have it drained and treated? My doctor is on vacation and suggested I take aleve and wait and see.
