Dr. Li Mingchuan
Testicular pain and lower abdominal pain are generally caused by left-sided epididymitis. Patients can undergo color Doppler ultrasound, which may show testicular enlargement and increased blood flow to the testicle. In cases of left testicular torsion, inflammatory substances produced can also irritate the testicle, causing testicular pain. Untreated conditions such as urethritis, urinary tract infections, and prostatitis may lead to chronic inflammatory diseases of the urinary tract, which are the main causes of left-sided testicular pain.
