Ok so I was bending down in a kneeling position to get a pan out of a cubord when my knee got a sudden and sharp pain to the lower outside part of my right knee. It started to swell after a few minutes (or at least that's when I noticed) it took me a few to get up and straighten my knee. It is still giving me sharp pains as I walk or bend it. Have a stability knee brace that I use from time to time to relieve the normal pains in my knee from jump school in the army. It has never hurt this bad before so it has me worried. It's usually just swelling and discomfort after a run. On a scale of 1 to 10, 10 being the worst pain I've ever had I'd give it an 8.
