Hit my knee during soccer. there was no popping or initial pain. then the inside part of knee started hurting. when i press on my knee and when i fully extend the inside/upper part of my knee hurts. wondering if its a bone bruise or something else?

It could be a soft tissue contusion vs bone contusion. For the latter condition, it may take weeks to months for a full recover. With soft tissue bruise, your symptoms should resolve in a couple weeks. If symptoms persist or get worse after 6-8 weeks, you should be evaluated by an orthopedist. If current activity is limited due to pain, you should wear a knee brace and take advil OTC as needed.
