Hi
Lower right quadrant
abdominal pain may be caused by many medical conditions involving the digestive tract, urinary tree and the genitalia.From the result of your ultrasound, organic pelvic causes can be eliminated.Some common causes include:
1.Digestive Tract problems: appendicitis,
cholecystitis,
diverticulitis, inguinal hernia, bowel obstruction,
gastroenteritis and abdominal masses.
2.Urinary problems : UTI, kidney stones,
3.Gynecological problems: poorly treated
Pelvic inflammatory disease given fluid in your pouch of Douglas.
With all these possible causes, only a keen evaluation by a doctor with some lab tests and abdominal ultrasound will help to bring out the exact cause.
You will need to see the Doctor for evaluation and work-ups like a stool exam, urinalysis, and abdominal ultrasound.In the meantime, if the pain is too intense, pain medication like ibuprofen may help.
Hope my answer will help you
Best regards
