Differential Diagnosis for Pain in Right Lower Abdominal Region Exacerbated by Movement
- Single Most Likely Diagnosis
- Appendicitis: This is the most common cause of acute right lower quadrant abdominal pain, especially when exacerbated by movement. The pain often starts near the navel and then moves to the right lower abdomen.
- Other Likely Diagnoses
- Ovarian cyst or torsion: These conditions can cause severe pain that worsens with movement, especially in females.
- Ectopic pregnancy: Although less common, an ectopic pregnancy can present with abdominal pain, including right lower quadrant pain, and is exacerbated by movement.
- Intestinal obstruction: This can cause abdominal pain that worsens with movement due to the increased pressure and tension on the intestines.
- Kidney stone: A stone in the right ureter can cause severe pain (renal colic) that may radiate to the right lower abdomen and worsen with movement.
- Do Not Miss Diagnoses
- Ruptured ectopic pregnancy: This is a life-threatening condition that requires immediate medical attention. Although it may not be the most likely diagnosis, missing it can be fatal.
- Ruptured appendix: If appendicitis is not treated promptly, the appendix can rupture, leading to peritonitis, a life-threatening condition.
- Ovarian torsion: Failing to diagnose ovarian torsion can result in the loss of the ovary due to lack of blood supply.
- Intestinal ischemia: Reduced blood flow to the intestines can cause severe abdominal pain and is a medical emergency.
- Rare Diagnoses
- Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis): These conditions can cause chronic abdominal pain, including right lower quadrant pain, but are less likely to present acutely with pain exacerbated by movement.
- Right lower lobe pneumonia: Although pneumonia typically presents with respiratory symptoms, it can cause referred abdominal pain, especially if the diaphragm is involved.
- Abdominal wall hernia: A hernia in the abdominal wall can cause pain, especially if it becomes incarcerated or strangulated, but this is less common in the right lower quadrant.
