One day, you start having this pain on one of your sides, just below your rib cage, starting in your back and wrapping around to the front. It’s very painful, but you don’t notice anything wrong in the area, so you put up with the pain and go about your day. It’s still painful a few days later, but now you notice a red-colored rash in the area. What is it? Do you need to go to the doctor?
