1. Understanding Left Testicle Pain and Its Possible Causes

Left testicle pain when sitting can stem from various underlying issues, ranging from minor discomforts to more significant medical conditions. Identifying the cause is the first step toward finding relief and ensuring your overall health.

Varicocele: One of the most common causes of left testicle pain is varicocele, an enlargement of the veins within the scrotum.
Epididymitis: Inflammation of the epididymis, the coiled tube at the back of the testicle that stores and carries sperm, can cause pain.
Testicular Torsion: A medical emergency in which the testicle twists, cutting off its blood supply.
Hydrocele: A fluid-filled sac surrounding a testicle that causes swelling in the scrotum.
Inguinal Hernia: Occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles.
Testicular Cancer: Though less common, testicular cancer can sometimes present with pain or discomfort.
Nerve Issues: Nerve compression or irritation in the groin area can sometimes cause referred pain to the testicle.
Trauma: Injury to the testicle or scrotum can result in pain.
Kidney Stones: Pain from kidney stones can sometimes radiate to the groin and testicle area.

Each of these conditions has unique characteristics and requires different approaches for diagnosis and treatment. Let’s delve deeper into each of these causes to give you a better understanding of what might be happening.

2. Varicocele: A Common Cause of Left Testicle Pain

Varicocele illustration showing enlarged veins in the scrotum

A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. This condition is more common on the left side due to anatomical differences in how the veins drain.

2.1. What is Varicocele?

Varicoceles occur when the valves inside the veins in the scrotum malfunction, preventing blood from flowing properly and causing it to pool. This leads to enlarged veins that can cause pain and discomfort.

2.2. Symptoms of Varicocele

Dull ache or discomfort in the testicle
Pain that worsens with standing or physical activity
Swelling in the scrotum
The feeling of a “bag of worms” in the scrotum
Infertility (in some cases)

2.3. Why Does Varicocele Cause Pain When Sitting?

Sitting can increase pressure in the pelvic region, which can exacerbate the pooling of blood in the enlarged veins of a varicocele. This increased pressure can lead to greater discomfort and pain.

2.4. Diagnosis of Varicocele

A physical exam is usually the first step in diagnosing a varicocele. The doctor may feel the enlarged veins in the scrotum. An ultrasound of the scrotum can confirm the diagnosis and rule out other conditions.

2.5. Treatment Options for Varicocele

Observation: If the varicocele is small and not causing significant pain, observation may be recommended.
Pain Management: Over-the-counter pain relievers and supportive underwear can help manage discomfort.
Varicocelectomy: Surgical removal of the affected veins.
Varicocele Embolization: A minimally invasive procedure in which a catheter is used to block the affected veins.

Varicocele embolization, offered at facilities like Azura Vascular Care, is a less invasive alternative to surgery with a shorter recovery time.

3. Epididymitis: Inflammation and Pain

Epididymitis is the inflammation of the epididymis, the coiled tube at the back of the testicle that stores and carries sperm. This condition can cause significant pain and swelling in the testicle.

3.1. Causes of Epididymitis

Bacterial Infection: Often caused by sexually transmitted infections (STIs) such as chlamydia or gonorrhea.
Non-Infectious Causes: Can result from urine reflux into the epididymis, trauma, or certain medications.

3.2. Symptoms of Epididymitis

Testicle pain and tenderness
Scrotal swelling
Redness and warmth in the scrotum
Painful urination
Discharge from the penis
Fever

3.3. How Sitting Can Affect Epididymitis Pain

Sitting for prolonged periods can put pressure on the scrotum and surrounding tissues, which can exacerbate the pain associated with epididymitis. This is because the inflamed epididymis is sensitive to pressure and movement.

3.4. Diagnosis of Epididymitis

Physical Exam: A doctor will examine the scrotum to look for signs of inflammation and tenderness.
Urine Tests: To check for bacterial infections.
STI Screening: If a sexually transmitted infection is suspected.
Ultrasound: To rule out other conditions such as testicular torsion.

3.5. Treatment of Epididymitis

Antibiotics: For bacterial infections.
Pain Relievers: Over-the-counter pain relievers can help manage discomfort.
Supportive Underwear: To reduce pressure and support the scrotum.
Rest: Avoiding strenuous activity.

Testicular torsion is a medical emergency that occurs when the testicle twists, cutting off its blood supply. This condition requires immediate medical attention to prevent permanent damage to the testicle.

4.1. What is Testicular Torsion?

Testicular torsion happens when the spermatic cord, which carries blood to the testicle, becomes twisted. This twisting cuts off blood flow, leading to severe pain and potential tissue damage.

4.2. Symptoms of Testicular Torsion

Sudden, severe testicle pain
Scrotal swelling
Nausea and vomiting
Dizziness
Abdominal pain

4.3. Why Immediate Treatment is Necessary

Without prompt treatment, testicular torsion can lead to irreversible damage to the testicle within hours. This can result in infertility and the need for surgical removal of the testicle (orchiectomy).

4.4. Diagnosis of Testicular Torsion

Physical Exam: A doctor will examine the scrotum and testicles.
Ultrasound: To assess blood flow to the testicle.
Surgery: In some cases, surgery may be necessary to confirm the diagnosis and correct the torsion.

4.5. Treatment of Testicular Torsion

Surgery: The primary treatment for testicular torsion is surgery to untwist the spermatic cord and restore blood flow to the testicle.

Time is of the essence when it comes to testicular torsion. If you experience sudden, severe testicle pain, seek immediate medical attention.

5. Hydrocele: Fluid Accumulation in the Scrotum

A hydrocele is a fluid-filled sac surrounding a testicle that causes swelling in the scrotum. While usually not painful, it can cause discomfort and heaviness.
