i fell/jumped off the back of a car that was moving it wasn t going very fast but the landing must have injured my left knee. I was limping for a week, i thought i had bruised my knee or maybe tore something but i didn t think it was bad it has been three or four months now the knee is still tender the to touch kinda feel like a bruise not a bad one though. There is pain but i would categorizes it as nothing above a 5 i have been walking on it since the injury, i sometimes notice i favor the knee when i go to kneel i without thinking about will try not to put weight on it and i don t understand it doesn t really hurt to kneel, the pain is more noticable after sitting for extended periods of time. I ve done a little bit of research and it seems to be pointing to a possible fracture. Do i really need to go to the doctor its been so long since the injury and what would happen if i decided not to seek medical attention
