How do you diagnose this sudden abdominal pain (Acute Abdomen)?

- Exactly where the pain is: It hurts somewhere in the stomach.
- Time of onset of pain and a description of the pain: When did it start and what kind of pain is it (aching, cutting, squeezing).

If a digestive or prostate problem is suspected, a digital rectal exam may be performed. If a gynecological problem is suspected, a pelvic exam may be performed. If a testicular torsion is suspected, a testicular exam may be performed.
Based on your answers to these questions and the findings from the physical examination, the doctor can get an idea of what the illness might be. Based on that, he will decide what diagnostic tests to perform.
What kind of tests are done for this?
Sometimes, if your doctor can clearly identify the cause of your symptoms, he or she may be able to refer you directly to surgery without any further testing.

The tests you will need to do will depend on what you find during your physical examination and the suspected condition.
