Has this ever happened to anyone out the? I have enough medical problems causing bad pain. But right below my mid back on my spine, I am sure it can be any where on some else as long as it's on the spine, that a black and blue mark just suddenly appears. I haven't had any accidents, haven't hit myself. Just out of nowhere, this pain came out and it felt like a bruise. And my wife said it was there over my spine. Nothing is tingling or anything. I thought maybe I could have broken one of those pieces of spine that stick out by themselves. My brother did that, but he is active. I have a lot of arthritis in my back but not rheumatoid. I also have some stenosis. I pretty much have arthritis on every X-ray I have had done. Well, if anything comes to mind, please let me know, if not, I will just leave it alone and let it heal.
