Differential Diagnosis for Yellow Vaginal Discharge and Supraubic Pain
Single Most Likely Diagnosis
- Bacterial Vaginosis: This condition is characterized by an imbalance of the normal vaginal flora, leading to an overgrowth of bacteria. It often presents with a yellow or greenish, fishy-smelling vaginal discharge. The supraubic pain could be related to the infection spreading to the urinary tract or causing pelvic inflammatory disease (PID), although the pain is more commonly associated with other conditions.
Other Likely Diagnoses
- Trichomoniasis: A sexually transmitted infection caused by the parasite Trichomonas vaginalis, which can lead to a yellow-green, frothy vaginal discharge and pelvic pain.
- Pelvic Inflammatory Disease (PID): An infection of the female reproductive organs that can cause lower abdominal pain, including supraubic pain, and abnormal vaginal discharge.
- Urinary Tract Infection (UTI): While UTIs primarily cause dysuria and frequency, a severe infection can lead to supraubic pain and, if the infection ascends, could potentially cause changes in vaginal discharge.
Do Not Miss Diagnoses
- Ectopic Pregnancy: Although less likely, an ectopic pregnancy can present with abdominal pain and vaginal bleeding or discharge. It's a medical emergency that requires immediate attention.
- Ovarian Torsion: A condition where the ovary twists around its ligaments, cutting off blood supply. It can cause severe pelvic pain and might be accompanied by vaginal discharge if there's an associated infection or cyst rupture.
- Appendicitis: While primarily causing right lower quadrant pain, an inflamed appendix can sometimes cause more generalized or supraubic pain, especially if it's retrocecal. Vaginal discharge might not be directly related but could be a coincidental finding.
Rare Diagnoses
- Gonorrhea: A sexually transmitted infection that can cause yellow vaginal discharge and pelvic pain, though it's less common than other causes.
- Chlamydia: Similar to gonorrhea, chlamydia is a sexually transmitted infection that can lead to pelvic pain and abnormal vaginal discharge, but it often presents with fewer symptoms.
- Vaginal Cancer: A rare condition that could potentially cause abnormal vaginal discharge and pelvic pain, though it would be an unusual presentation for this cancer.
