I had a MRI that revealed a 4 -5 cm by 2-3 cm black spot under my left shoulder blade. The doctor said it was either a cyst or a tear. I typically do not have pain during the day, but at night when I lay down, the pain is excruciating. Hurts worse than anything I have ever felt. Wondering what it could be. At times I think its an infection because I start sweating, then I get hot, then I start sweating, then I get hot almost like I am getting a fever than breaking the fever. Other times I wonder if it is cancer as once the pain starts, my left arm feels dead and even my ear to my ribs hurt. It is a weird set of symptoms. I am scheduled to see a ortho surgeon tomorrow.
