question: Hi.My boyfriend had hernia and the doctor did a surgery on him.  now his stomach aches and he has a black spot on the stomach lining or wall of the stomach. What does that mean and what is the solution to his health issue. I am trying2find solutions for him in addition to his next visit to his doctor. Does he have an ulcer?  He complained of alotta pain, nausea, restless nights.  It's not easy on me to hear of his health condition, so this is my way to possibly give him more valuable information.
