Referred pain?

I really can't tell if the pain is from my hip, from my thigh(which generally means it's muscles or other soft tissues), or if it's my knee. I know hip pain can result in referred knee pain, but this is getting me discombobulated because the pain i'm experiencing now is rather peculiar... *hmm*

p.s. I think i do tend to overuse the word 'really'... Bad habit!
