I fell almost three months ago on my right knee. I got right up and continued the day. Ofcourse the knee hurt. When I was bending on my knees on the floor, the right knee was very painful. I thought it was temporary and would go away as my knee healed. There are no bruises on my knee and it gives me no problem EXCEPT when I am on the floor on bended knees and the pain below my knee (between top of shin and knee) is excruciating. But no pain otherwise.. Any ideas???
