What is Hip (pain)?

Well, I was hoping to have a positive post here, but to no avail. My hip is a real problem. I got in touch with the wonderful Coach Dror and he gave me a new "get off yer butt" regime to follow. The first night, I was running like a pro (well, at least as well as I've been doing) and, not 15 minutes later, my hip was screaming at me. I don't know what to do. I did 5 miles a few weeks ago, walking even, and the hip hurt. I don't know what to do. I am almost tempted to stop running altogether (but doing other cardio) until the race. I have track practice (finally I can get there again!) on Thursday, so hopefully I can try to find a remedy. I do feel like a big slacker though!
