Torn Knee Cartlidge?

[Nowwhat215]

Ive been running for about 3 months now..the last 2-3 weeks ive been having knee pains that are causing my running to go down the drain. I do decent on my first 5-6 laps making about 1.45 minute pace. Then the last 2-3 laps my knee starts burning and feels like it is going to buckle..kinda feels like its hyperextended but i know its not or it would be hurting from lap 1. after my run is over i limp around for a few hours like a gimp!! i has anyone ever had any problems like this? has anyone had symptoms like this with torn cartlidge?

Do you have a damaged cartilage or you just thik you have? Please be more precise, what pain is it and most important where it is, onder the knee cap, over the knee cap, on the inside/outside etc. The knee is one tricky bastard of a joint, it's built is comlicated and there are a lot of different injuries that can happen. However there is a formula for knee injurues: knee+pain=see a doctor.
