Walking issues, HELP PLEASE!

I am a fit and healthy 13 year old girl. Before this recent summer I have been fine walking and running without any issues until this summer. I was running and my hip felt like it had fallen out of place. I couldn't walk or run. This happens every time I run or it will just happen randomly. Now it has moved down to my left leg around my knee cap area.
I struggle to walk when this happens and I limp to walk around. Especially at p.e. time at school I struggle to walk and most of the time I have to sit out because I am afraid that it will pop out again. It is really getting on my nerves!!! Does anyone know what I can do???


P.s. I can bend my leg but I can't put any weight on it.

Get it checked out by a doctor :)

Those have walking issues they should not go for visit to African countries. Walking is the most important to climbing mountain and pass the way where there is no way for vehicles. http://www.one-waytoursandsafaris.com
