Why Does My Right Testicle Hurt?

Testicular pain is usually caused by orchitis or testicular injury. Orchitis is generally caused by pathogen infection. In addition to blood-borne infection, it is more common for bacteria to enter the epididymis and testis through the urethra, causing epididymitis or orchitis. There are also many other causes of testicular pain. Some people experience pain in the right testicle. It is important to rest and maintain a good mood. What causes pain in the right testicle? Let's take a look.

I. Causes of Right Testicular Pain

1. Trauma to the testicle causing pain.
2. Nerve compression and irritation due to lumbar disc disease, which may cause testicular pain.
3. Acute or chronic inflammatory diseases in the right epididymis can cause testicular pain.
4. Varicocele or inflammation of the spermatic cord on the same side can cause testicular pain, accompanied by pain in the groin area.

II. Testicular Pain

Testicular pain is most commonly seen in orchitis and testicular injury. Orchitis is mostly caused by pathogen infection. In addition to blood-borne infection, it is more common for bacteria to enter the epididymis and testis through the urethra, causing epididymitis and orchitis. Clinically, swelling and pain of the epididymis and testis can be observed. Testicular injury usually has a history of trauma and local swelling and hematoma. Vigorous exercise, sexual activity, or violence can sometimes cause intense contraction of the cremaster muscle, leading to torsion of the testis with an overly long mesorchium and severe testicular pain. Chronic pain can persist for a long time, with mild and generalized pain that can be radiating.

III. Symptoms of Testicular Pain Caused by Different Reasons

1. Infection can cause severe testicular pain, even like a knife cutting, accompanied by systemic symptoms such as fever and chills. At this time, the scrotum is red and swollen, and touching the testicle causes more obvious pain.
   • Tuberculous infection: often accompanied by a history of tuberculosis in the urinary system or other parts of the body, manifesting as dull testicular pain, a feeling of fullness and distension in the lower abdomen, and scrotal swelling. Severe cases may result in the discharge of pus. When touching these lesions, there may be uneven nodules that are hard and often adherent to the scrotal skin.
   • Prostatitis: can cause testicular pain accompanied by a feeling of discomfort and fullness in the perineum, as well as symptoms such as frequent urination, urgent urination, painful urination, and difficulty urinating.
2. Non-infectious causes of chronic testicular pain may be due to varicocele or radiating pain from other parts of the body.
