Shingle Pain is bothering me?

I am a 17 year old male. I had shingles 2 years back. My skin had cleared up but the excruciating pain persists. I went to the doctor and he told it may never go away and there is no cure. He said he will give me a shot for that like a anti something shot i don't remember. I hope that helps. I cant believe that at a young age i have this. I cant believe i have this at all. I would do anything for this pain to go away. Even if it means surgery. But i don't want to feel this pain at all. What should i do?
