    Dull pain in the left testicle may be related to factors such as varicocele, epididymitis, testicular torsion, urinary system infection or trauma. Testicular pain usually manifests as local swelling, referred pain, or sudden severe pain. The specific cause needs to be determined based on the accompanying symptoms.

    1. Varicocele

    Obstruction of spermatic vein return may cause swelling and pain in the left testicle, which worsens after standing for a long time or exerting force. Physical examination shows vermiform varicose veins on the scrotal surface, and ultrasound examination can confirm the diagnosis. Mild cases can be relieved by scrotal support, while moderate to severe cases require laparoscopic high spermatic vein ligation. Avoiding prolonged standing and strenuous exercise can help improve symptoms.

    2. Epididymitis

    Retrograde bacterial infection of the epididymis can cause persistent dull pain in the affected testicle, which may be accompanied by fever and frequent urination. Physical examination showed palpable epididymal enlargement with tenderness, and blood routine showed elevated white blood cells. In the acute stage, bed rest is required, and antibiotics such as levofloxacin tablets and cefixime dispersible tablets are used as directed by the doctor, along with cold compresses on the scrotum to relieve swelling.

    3. Testicular torsion

    Sudden severe pain in the testicles accompanied by redness and swelling in the scrotum requires vigilance and rotation, and the golden period for treatment is within 6 hours. The spermatic cord rotates due to the excessive length of the testicular mesentery, and ultrasound shows that the blood flow signal is weakened. Surgical reduction and fixation should be performed immediately after diagnosis. Delay in treatment may lead to testicular necrosis. Teenagers who experience sudden pain after strenuous exercise should seek medical attention immediately.

    4. Urinary system infection

    Prostatitis or urethritis may cause radiating pain to the testicles, often accompanied by a burning sensation during urination. Routine urine examination shows an increase in white blood cells, and bacterial culture can identify the pathogen. You can follow the doctor's advice to take Tamsulosin Hydrochloride Sustained-release Tablets and Sanjin Tablets for treatment, and at the same time drink more than 2000 ml of water every day to promote bacterial excretion.

    5. Trauma or strain

    A straddling injury or sports impact may cause testicular tissue contusion, which may manifest as a dull pain that gradually gets worse. Minor injuries can be relieved by bed rest and cold compresses on the scrotum. If enlargement persists, ultrasound is required to rule out testicular hematoma. It is recommended to wear protective equipment during exercise to avoid secondary injuries.

    If you experience dull pain in the testicles, you should avoid applying heat or applying pressure on your own, and promptly seek medical advice from a urology department to complete scrotal ultrasound and routine urine examinations. Pay attention to keeping the perineum clean and dry every day, choose breathable cotton underwear, and avoid compressive activities such as riding a bicycle for long periods of time. Suspend sexual intercourse during acute pain, eat a light diet and avoid spicy foods, and observe changes in symptoms with follow-up examinations.
