No dramas,
The first thing you should know about snapping hip and most knee pain (ITBFS or something similar might be the cause of your lateral knee pain, which ties in with our current ideas of your ITB being a problem) is that you should immediately decrease ALL aggravating activities over all else.

So yes the exercises below might help, but only ones which do not cause pain. So forget the squats etc. Might be better to do some VMO activation exercises lying in bed etc. have a look for some on the net. If you can't find any I can try and type you up a program.

Have a read of that article and look for some exercises etc. then let me know if you are still stuck with ideas. Don't just passively think it will take time and not do anything about it. It will likely not improve.

We are here to help remember!
