I know that you guys will not be able to give me an "actual" answer or diagnosis- I'm just wondering if anyone has any speculations as to what might be the problem.
About 7-8 years ago, I was jogging out to my car in the dark to grab something. I caught my shin on a high, long trailer hitch and fell down- landing on my left knee. I think the impact was sort of around the top of the knee cap.
It hurt quite a bit after it happened- but I also have a high pain tolerance. I figured I had bruised myself pretty bad and it just take it's course and that would be that.
I did not go to the DR (thanks to my high pain tolerance)- every year since then, it has sort of "acted up" in the winter- but once again, not quite enough to send me running to the DR. It gets warm and starts to ache if I bend it for extended periods of time.
Now, it's starting to bother me when I walk up the stairs and or bend down (probably doesn't help that I have my son in tow usually). The pain seems most intense at the top of the knee cap, and it sort of feels like it's radiating up my leg a bit.
Any vague ideas?
