3-4 months ago my knee got caught between a pipe gate and a pipe fence. Cattle came off a trailer and pushed the gate and my leg got caught. It hurt so bad I thought I was going to pass out. After a while I felt better and determined that I hadn t broken any bones and went on with life. I can exercise and lift weights and do daily life without pain, but if my pants brush on the inside of my knee it is extremely painful. When I sleep on my side at night I have to be careful to position my knee so that it. Isn t resting on anything. Very painful to touch. Can t figure out what kind of damage has happened and if it will go away with out treatment.
