What could cause pain in the right testicle and lower abdomen at the same time?

Pain in the right testicle accompanied by lower abdominal pain may be a sign of appendicitis. While appendicitis typically causes pain around the belly button that shifts to the lower right abdomen, the pain can sometimes radiate to the right testicle or scrotum, especially in men. Other possible causes include testicular torsion, epididymitis, kidney stones, or an inguinal hernia—several of which are medical emergencies.

Because these conditions can escalate quickly and share overlapping symptoms, identifying the cause early is critical. A free, instant, online symptom check can help you clarify what's likely behind your discomfort, assess urgency, and guide your next steps—so you can decide whether to seek emergency care, book a doctor's visit, or monitor at home with confidence.

Explanation

Pain in the right testicle and lower abdomen may be caused by a condition called appendicitis. In some cases, appendicitis, which is an inflammation of the appendix, can present with pain that is felt in the scrotum or testicle area. This can happen because the nerves that supply the appendix and the scrotum may have connections that cause pain to be felt in both areas.

Here are some key points:

Appendicitis: This is when the appendix, a small tube attached to the large intestine, becomes inflamed and painful. It usually causes pain in the lower right abdomen.
Referred Pain: Sometimes, the pain from appendicitis can be felt in the testicles. This is called referred pain, and it happens because of the way nerves are connected in the body.
