### Patient: Doctor, I have this open wound on my abdomen and I'm experiencing sharp abdominal pain. I also can't see anything. Can you tell me what's wrong with me?
### Doctor: It sounds like you are suffering from a perforated ulcer, which is a hole in the stomach or small intestine. The abdominal pain and wound are from the ulcer, while the blindness may be due to complications of the disease. We need to operate on you immediately.
