Differential Diagnosis for Sharp Pains in Lower Left Side of Abdomen during Pregnancy
Single Most Likely Diagnosis
- Round Ligament Pain: This condition is a common cause of sharp, intermittent pains in the lower abdomen during pregnancy, especially in the second and third trimesters. The pain is usually located above the pubic bone and can radiate to the inside of the pelvis, consistent with the patient's symptoms.
Other Likely Diagnoses
- Braxton Hicks Contractions: These are practice contractions that can cause sharp pains in the abdomen, often feeling like strong menstrual cramps. They can occur at any time during pregnancy but are more common in the second and third trimesters.
- Urinary Tract Infection (UTI): A UTI can cause sharp pains in the lower abdomen, often accompanied by other symptoms like burning during urination, frequent urination, and cloudy or foul-smelling urine.
- Constipation: Constipation is common during pregnancy and can cause sharp, intermittent pains in the lower abdomen due to the pressure of stool in the intestines.
Do Not Miss Diagnoses
- Placental Abruption: Although less likely, placental abruption is a serious condition where the placenta separates from the uterus, causing severe abdominal pain, vaginal bleeding, and potentially life-threatening complications for both the mother and the fetus.
- Preeclampsia: Characterized by high blood pressure and often accompanied by protein in the urine, preeclampsia can cause abdominal pain, among other symptoms. It is a condition that requires immediate medical attention to prevent severe complications.
- Appendicitis: Although the location of the pain might not be typical (usually appendicitis causes pain in the lower right abdomen), an inflamed appendix can sometimes cause pain that is more centralized or on the left side, especially if the appendix is located in an unusual position.
Rare Diagnoses
- Ovarian Cyst or Torsion: Ovarian cysts can cause sharp pains if they rupture or torsion occurs. While less common during pregnancy, these conditions require prompt medical evaluation.
- Ureteral Stone: A stone in the ureter can cause severe, sharp pain (renal colic) that radiates from the flank to the groin. Although not exclusive to pregnancy, the symptoms can sometimes be confused with other pregnancy-related conditions.
