What are the possible causes of dull pain in the lower right abdomen?

In daily life, many people experience dull, persistent pain in the lower right abdomen, yet the exact cause often remains unknown. So, what are the possible causes of dull pain in the lower right abdomen?

Causes of Dull Pain in the Lower Right Abdomen

Right adnexitis: Typical symptoms of right adnexitis include pain in the lower right abdomen, which tends to worsen with physical exertion or exposure to cold. Additional symptoms may include fatigue, low-grade fever, and general lethargy.
Ectopic pregnancy: In women of childbearing age presenting with dull, persistent pain in the lower right abdomen, ectopic pregnancy should be considered. Rupture of an ectopic pregnancy commonly leads to abdominal pain and vaginal bleeding.

Intestinal tuberculosis: Typically caused by infection with Mycobacterium tuberculosis, intestinal tuberculosis commonly manifests as lower right abdominal pain, vague periumbilical discomfort, palpable abdominal mass, and altered bowel habits.
Right distal ureteral stone: The initial symptom of a stone lodged in the distal segment of the right ureter is abdominal pain, which may radiate progressively to the ipsilateral inguinal region, scrotum (in males), or labia majora (in females), resulting in widespread referred pain.

Duodenitis: Often caused by bacterial or parasitic infection, duodenitis primarily presents with abdominal pain, nausea, and vomiting. Severe cases may also involve bloating and belching—symptoms indicative of dyspepsia.
Appendicitis: Though relatively uncommon, appendicitis can produce various symptoms, including lower right abdominal pain, nausea, vomiting, low-grade fever, and loss of appetite. Accurate diagnosis of the underlying cause is essential to guide evidence-based treatment, thereby alleviating pain and restoring health. Additionally, it is important to protect the abdomen in daily life—avoiding trauma or exposure to cold temperatures. We hope this information has been helpful to you!
