My wife has had pain in the area below the left shoulder for the past week. The pain is there even when she deep breathes, moves her left hand, or does any movement. She is a feeding mother, has overweight, and had a cesarean delivery a year ago. She had a similar complaint but reduced after rest. But this time, it has not reduced. We tried an external application of counter pain and used a hot water pack. She suspects that she sleeps on one side during feeding, which is causing this problem. I have attached the image of the area where she has pain. Please help.
