What is your age? Are you having any other symptoms?
Have your bladder or bowel habbits changed lately? It is not that you are wasting doctor's time.
You need to consult a doctor to rule out appendicitis, kidney stones, diverticulitis, crohn's disease, pelvic inflammatory disease etc.
The further plan of management would involve -
'-Blood tests including full blood count, electrolytes, urea, creatinine, liver function tests, pregnancy test and lipase.
-Imaging including erect chest X-ray and plain films of the abdomen
-An electrocardiograph to rule out a heart attack which can occasionally present as abdominal pain
If diagnosis remains unclear after history, examination and basic investigations as above then more advanced investigations may reveal a diagnosis. These as such would include
-Computed Tomography of the abdomen/pelvis
-Abdominal or pelvic ultrasound
-Endoscopy and colonoscopy'
