What kind of problem is this?

My leg seems to have been hurting for over 5 months now. The doctor said it should heal in 2 weeks 5 months ago xD! But he didn't know whats wrong, really I dont think anyone does not even me O.o

But anyways, it hurts insanely bad xD! I've been loosing sleep because of it. Getting around, maybe 2-3 hours of sleep a night, then going back to be for a short nap (Sometimes) like maybe a few hours later. Sometimes I can be lucky and get a lot of sleep when I pray :D
