I dislocated my right knee a few weeks ago and haven't done too much since. I've been resting on a couch with very limited movement and usually I am able to do very simple things like go to the bathroom or get something to eat. Yesterday when I was in the bathroom standing up, I had a very weird sensation in my knee. It didn't hurt too bad, just felt strange and made me feel extremely paranoid. Now it's been 10 hours since I've gotten up and I have to go to the bathroom very, very badly but I'm afraid something bad will happen if I walk on it. Am I being too paranoid? Mind you, my leg is in an immobilizer but when this sensation occurs I feel the need to grab my knee because in my mind, it prevents something bad from happening. Can anyone help me?
