For quite some time I have had a burning sensation that I get on my back it used to come and go now it last much longer and everyday. Its located around the shoulder blade and literally feels like someone is putting a lighter to my back. It does not feel like internal pain at all.....it feels completely external. It has been getting to be almost unbearable, the pain medication my doctor prescribed me for a different back problem is barely doing anything anymore. I get it everyday almost on Q at about 6-7 in the afternoon. If I am hunched over at all like to type on my laptop it blazes. What can this be? Please help
