torn again?

Shucks....... think I torn my knee cartilage again. Been walking around these few days with a clicking feel in my left knee, just like how it felt before I went for surgery. Don't know how it became like this, did the doctor pull too hard during my last consultation? All I know was my leg became very sore the day after the consultation last week, and when the pain went away, the clicking feel was in my knee already. I'm bearing with it at the moment, do not wish to go through the agony of all the check-ups again. Hope it will recover by itself, but I'm not sure if it will. Probably will take a long time and lots of rest(which I do not have). Trying to walk very carefully nowadays to prevent further damage, so I'm kinda strolling all the time. Doesn't look good when people around me are working so busily, but I can't help it, I don't want to risk my knee. I guess that if this goes on, I'll probably go through another surgery within the next 5 years, either knee replacement or what. A 26-years-old man with a knee of a 62-years-old man, terrible....... Can't imagine the day when I need to carry someone, be it being sweet to my other half or in case of an emergency. Don't think my knee can take it. Bless my knee......
