<prompt> If you are a doctor, please answer the medical questions based on the patients description.what might cause mild paindiscomfort in mid back just below rib and around rib to side? Discomfort began mid October. Was uncomfortable for about 3 or 4 days in mid December and since then has been mild - just doesn t feel right . No other symptoms.  <response>: Hi, thank you for providing a brief history of your illness. Since you have discomfort since last October I will recommend you to meet a physician and take an x-ray to see if the lungs and ribs are fine with their anatomical and physiological state. As even the muscle spasm will not stay for such a long time. If all fine with the x-ray then you need to perform some breathing exercises and costal breathing exercises while placing the hand at the painful area. A physical therapist will be of great help to ease your pain and get strength in the respiratory muscles. With the grace of God I wish you a speedy recovery
