Hi I was playing soccer with my friends the one day and I dove to save the ball and I as went to get back up quickly it felt as if my knee got out of its normal position. It hurt really bad and then instead of getting back up I stayed down and it went back my knee cap doesn't hurt but the inside side of my knee hurts and can't bend well. Ater about 2 weeks since this incident my knee is able to bend almost fully but not completely and still had some pain what could have happened?

You had a sprain or a strain... and luckily nothing worse. A week or more is the usual time to get past those.

I've hyperextended my knee before twice... both times those set unprecedented levels on the person pain meter.

Should I go see a doctor because this happened about 4 weeks ago or not? Also during a soccer game maybe 2 months ago a kid went cleats up and hit my hip with the cleat. I played on but with pain and then afterward my hip began to really hurt. The next game I got hip checked by some really skinny kid and that one I really felt it I could not run without pain or walk at times and it wasn't good. It turned red and really hot and purple I put on icy hot on it. Till today it hurts at time and I try to strecth it out but it causes pain. I try to put pressure on it and it feels like the muscle or tissue is really squishy but then there's like a boney feeling that seems cracked. I don't know what it could be any ideas?

Would not hurt... but you really should have done that when it happened a month ago. At least you will have the benefit of a doctor who can examine you in person. There is no substitute for that.

Certain types of injuries are important to diagnose and attend to BEFORE healing starts...
