I have been searching for the episode  where a woman suffering from chronic , severe head pain, finally found a doctor who  discovered she had a pinched nerve in her head caused by a blood vessel  had wrapped around a nerve, he performed surgery and simply moved the two apart from each other.  ...this may be  the solution I need! 
who was the doctor?
How can i contact him / her?
what was her condition called? 
where can I read and watch the episode?

Depending on where it is at it can be very bad. From the pic I'm going to say that its on your forarm right?

I would go and have you Dr look at it but in that area it should heal its self. I had one bust in my eye and almost made me loss that eye.

I hope that helps you.

This happened to me one time. I was sitting down and I felt this weird sensation on my knee. I was wearing shorts so I looked at my knee and a blood vessel on the top of my knee cap was "prominent" as if there was a tourniquet on my leg. I thought, "that's weird"! Then it exploded. Well, not explode, but it burst and the blood leaked out under my skin and my whole knee cap was blue. It looked extremely bruised and looked painful, but it wasn't painful at all. When I went to work the next morning, I asked one of the docs about it, and he said that it was normal and it happens sometimes for unexplained reasons. I'm sure you're fine.
