Knee hurting and popping(not at same time)?

My knee hurt around 2 years ago do to running which caused jumper's knee, then it came back in November. It all the sudden went away ( i was in a basketball game in a mob of players and i got out of it my knee was weak and it poped a lot) then it started to hurt on the medial part of my right knee. I went to EOOC and he said it was ok and the popping was from me growing. That was 4 months ago. My knee still hurts and pops many times a day. It is possible that I may have a micro tear in the patella tendon or a meniscus issue. Please help me understand. I'm 13, a girl, 5' 7" ish, muscular, not skinny but not morbidly obese. I also have a womens 11 size shoe. I'm still growing.
