For the past month and a half, I've been having this weird warm/burning feeling in my upper back and neck. I originally worried it could be from my stomach, like GERD, but now I'm not so sure. I'm scheduled to go in for an MRI sometime this month for my head, neck (which I usually get yearly for something unrelated), but now my mid back as well. I'm freaking out that I could have some sort of tumor in my spine. The feeling isn't really that bad, but it's been consistent all this time. Anyone have any experience with something like this?
