about a week i had troubles getting up and down stairs, bending my
leg, sitting, laying..anything that would make me lift that
leg or bend it, but to stand on it it really didnt hurt. about a week the pain went away but a week or so later somehow it started up again and then the other day i had to walk up a big hill, got home and since then my knee has been severely swollen and when i go to bend it, it feels like something is grinding and a lot of pressure...
