Hi and welcome to hCM.
Well it sounds like abdominal wall issue,not intraabdominal especially if this is sensitive to touch. YOu should do ultrasound
of this area to see is there any abscess
or muscle rupture. There can be intraabominal mass which presses abdominal wall but this is rare and more serious. If this is related to your digestion or more painful after meal then gastritis
or GERD should be considered and ensdocopy should be done. I suggest to do tests i ve mentoned if symptoms persist. Wish you good health.
