I have had pain in my right upper abdominal near the end of the sternum for 1 month. Generally, I don't have any symptoms but when I started walking mild pain is start in my right abdominal feels under my right rib. When I pressed this area feels better. I have done a chest x-ray and ultrasound but all is normal I don't know what happened please suggest to me what was causing it.
