Owww! Hyperextended Knee - remedies, please!? - knee sore driving

Hello people. I slept on the sofa with a rod on the arm of the sofa, bend your right knee slightly. I think I slept about three hours in this way. Since then, about three weeks my knee is very painful and prone to collapse.

I had knee probs as a child, and I am with an elastic bandage and the doctor told me then - below the knee, not above the kneecap, but it's still very painful. Any tips? I live in an area where a visit to the doctor two hours, more than three hours of waiting goes, so I prefer to avoid if I can. Thank you!
