Hit my knee in soccer. didnt pop but it has been a week and it hurts when i extend my leg all the way or when i press on it. right on the inside of my knee bone. wondering if it is just a bad bone bruise or something else concerning?

If the knee was swollen after the event but it has recovered with less pain, you probably had a bad knee contusion and it takes time for the pain completely resolves. You only need to be evaluated by an orthopedist after 6-8 weeks if knee's range of motion is still limited by then. Wearing a knee brace may be helpful in the mean time. Good luck.
