I had a lot of trouble with the muscle across my upper back, right below my neck, and after a while it felt like it was burning, especially if clothes rubbed against the skin, or someone touched my back there. When I asked the doctor why the muscle pain was suddenly making my skin feel like it was burning, she told me that it was normal, especially if that part of your back has been hurting or aching for several months. Evidently, the constant strain of the particular muscles that are hurting, eventually lead to a burning feeling in the skin that is in proximity to it.
Hope that helped you out a bit.
