I had a coughing fit, bent over to cough and somehow hurt my back. The pain started in my lower back on the right side. It spread to the entire right side of my back and shoulders. A few days later I found a small bump on my upper back near my neck on the side. It has been four days since then and it still hurts. I’m going to the doctor I’m a few days but if anyone knows anything then any advice would be appreciated.
