<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had surgery for a hernia that was located in the upper stomach area and lower breast area. My doctor repaired it and put mesh from underneath my breast area to about above my bellybutton. I am really hurting in the area of where my hernia was. Its been a little over 4 weeks since surgery.  <response>: Hi. Thanks for your query. Noted your history of hernia repair surgery with mesh 4 weeks ago for the upper left part of the hernia. The commonest causes of pain in such a case are:Nerve entrapment. Abscess formation. If intestinal symptoms are there, the intestinal obstruction. And so on. The diagnosis can be done by:- Clinical evaluation by a General Surgeon. Ultrasonography and the treatment will depend upon the cause thus found.
