Hi all. I've had one bad knee for years, resulted from twisting it while stepping off a ladder. Saturday, however, the OTHER knee was bothering me. Not major, just kinda felt pinched, like when you wear really tight jeans and have to bend a lot. Also noticed a couple times thru the day that the foot on the same side was numb. But again, wasn't enough that I really paid attention to it until late in the evening, when I was getting up and down helping difficult child with lego's. So I decided to look at it was HUGE. AS in, couldn't see I had a knee. I got off of it asap, took advil and iced it repeatedly. It was better yesterday, but I stayed down as much as I could. There is still some fluid on it, tho not nearly as much. It kinda hurts to touch in one spot, and every once in a while I'll bend it just right that really pinches something, but most of the time, it feels ok. How long should I give it before I see a doctor?
