At 20 I had shingles on my lower left side. A few weeks later a small burning feeling started to develop on my right shoulder blade. I am now 23 and the pain has only becom worse. I went to doctors and they said nerve damage. That was over two years ago. They gave me patches but those didn't help. Even now my blankets, putting on a shirt and even the slightest touch has an intense burning feeling. Could it still just be nerve damage?
