The list is endless with possible reason. The less serious would be bloating from gas, or constipation, or a symptom of PMS.
Gas is probably the most common cause of abdominal pain in the absence of any vomiting and diarrhea illness. Your will experience sharp pains on and off that may move throughout the abdomen. Sometimes you can feel the gas bubbles moving along.
Constipation can be painful in themselves, pain or discomfort from this comes in waves with little or no discomfort in between the pain.
Bloating or swelling of the lower abdomen may be present
in the lower abdomen below the navel from time to time, for instance, before or during menstruation, it may happen some months and not others.
Acute and sudden pains are always worrying some so to rule out anything serious your doctor should be consulted if pain persists. The doctor will ask about periods, passing of urine and bowel movements. They might also ask if there have been episodes of nausea, vomiting, or fever. If appropriate, they may ask questions concerning your sex life. Tests or treatment will be based upon the description of the pain and the findings of the doctor's examination. Most likely, a urine sample should be requested and tested for any signs of infection.
If a kidney problem is suspected than an ultrasound scan of the kidneys and bladder will be arranged.
If a problem with the womb or ovaries is suspected, swabs from the vagina looking for any infection might be performed and an ultrasound scan of the womb and ovaries is commonly performed.
If a bowel problem is suspected, a sample of the motion is often investigated for signs of infection and you may be recommended to have a telescopic examination of the bowel called an endoscopy.
If symptoms don't subside seek your dr for help and hopefully you'll be feeling better very soon.
Good Luck :)
