I was in a car accident 3 months ago. I had brusing on the inside of my right knee and also my ankle. Sometimes I feel a slight numbness when I touch my knee like shaving or kneeling. Usually my right leg doesn t bother me unless I m kneeling or have too much pressure on it. I now work at a daycare and if a small child jumps on my knee the right way I get pain. I have also been kicked there a few times. Lately my knee has bothering me more. I was diagnosed with arthritis years ago but I can tell the difference between my 2 legs and have never experienced this before.
