CHQ: SUBJECT: Pain
  MESSAGE: Sirs, I have a medical problem and I'd be very grateful if you can help. I feel some pain in the posterior area between the hip and the knee (as if there was something that stings). I noticed that the veins are prominent in this area. What can this be? What doctor should I see? Thanks for your cooperation,
Summary: What are the causes of posterior hip pain, and how can I find physician(s) who specialize in it?
