Hi, I have pain on my left side in my upper ribs. It has been there for a few weeks but is not getting better, it getting a little worse. I thought it was just a pulled intercostal at first so I left it. It is worse for breathing deep, coughing, yawning, and laying on it. It is better for taking voltaren tablets. Sometimes the pain goes though to my back and the same height/position. It affects me all day and my breathing is a little more shallow all day because of it.
