To anyone in the medical field I would appreciate your thoughts on this. I fell down Friday morning and hurt my knee and ankle. My ankle is still swelled up. I can walk on it but the swelling won't go down, only at night it goes down and then as I get moving around in the a.m. it swells up again. Could it be a sprain and if so how do you treat this? I can walk on it fine it just feels really stiff because it is so swollen. Also I fell on my knee and my knee cap is really sore. I could hardly bend it for a few days. I can bend it now but it still hurts really bad to touch it. It is really badly bruised. Is it possible to brake your knee cap? I have called my doctor and I have an appointment for tomorrow morning but I'm not sure if I really need to see him or not. Any advice would be greatly appreciated.
