Lateral leg/knee issues- help plz??!?

I play college basketball and for probably about the past 2 months, Ive been experiencing these sharp pains in my right leg. At first, I didn't think much about it; I just pushed it aside. Well, some 2 months later, Im still experiencing the sharp pains. A few weeks ago, the lateral part of my leg by the knee started hurting. When running, it would take me a while to get going, then I was good. It just hurt getting started to run and when I was standing still. I had the trainer look at it and he thought it was a worn out IT band. (Illiotibial Tract, i think). Thankfully, I had a 2 week Christmas break and just rested it. It feels better, but I still have the sharp pains that vary from my thigh to my knee. I got it looked at and the nurse practitioner did some tests and was pretty sure nothing was torn.....I started taking an anti-inflammatory medication, but these pains keep me up for a couple hours at night, just like lying in bed. Any suggestions or advice would greatly help!! Thanks!!

I'm 21 btw so I dnt think this is obviously normal lol
