I have no idea what this is. But knee is fine, pain free in day to day stuff. No symptoms and nothing physical to see.
Then I kneel down and it's like a red hot poker shoved inside my knee, gawd it hurts so much!
Yes I know I could just not kneel down, but with two DC's who like tickling and wrestling, we roll around lots. I kneel occasionally on hard tiled floor at work, for maybe a second at a time to get a file out, but the instant my knee touches the floor it's agony.
Any ideas?
