Hi doctor. I have a sharp pain on the right side of my abdomen about 3cm down from the side, every time I inhale air, my stomach hurts so what do I have? Looking forward to the doctor's answer.

The doctor told me that when my father went to the doctor, he discovered the lymph nodes in the head of the pancreas, so now is there any solution to limit the disease outbreak or how to treat the lymph nodes in the head of the pancreas?

I am male, 19 years old this year. Two weeks ago, when I went to the toilet, I saw that there were some black things in the stool, so I thought it was raw feces, although the stool was molded, it was very easy to break. When he went to the doctor, he was diagnosed with an intestinal infection. After taking the medicine, there was some improvement, but recently, the stools have appeared black pieces. I often feel uncomfortable in my stomach and want to have a bowel movement. Can you tell me if an intestinal infection is serious?
