Overview

Cold Sores
Cold sores are small, painful, fluid-filled blisters that usually develop on or around the lips and mouth. They are caused by herpes simplex virus and often recur after the initial infection because the virus remains inactive in nerve tissue. Outbreaks commonly heal within several days to a few weeks.
Orchitis
Orchitis is inflammation of one or both testicles. It may be caused by a viral or bacterial infection. Mumps is a well-known viral cause, while bacterial orchitis can occur with infections involving the urinary tract or reproductive system. Symptoms may include testicular pain, swelling, tenderness, fever, and fatigue.

Diagnosis

Cold Sores
Cold sores are usually diagnosed clinically from their characteristic appearance and symptoms, particularly grouped fluid-filled blisters around the lips or mouth. A healthcare professional may examine the affected area and ask about previous episodes and possible triggers. A swab or laboratory test may be considered when the appearance is unusual or the diagnosis is uncertain.
Orchitis
Orchitis is diagnosed using symptoms, medical history, and examination of the scrotum and testicles. Tests may include urine testing, blood tests, and testing for sexually transmitted infections when appropriate. Ultrasound may help distinguish orchitis from other causes of acute testicular pain, particularly testicular torsion, which requires urgent treatment.

Prevention

Cold Sores
Avoiding direct contact with active cold sores and not sharing items that contact the mouth can reduce transmission. During an outbreak, avoid kissing and oral contact with others until lesions have healed. Identifying and reducing personal triggers such as excessive sun exposure or fatigue may reduce recurrences. People with frequent or severe outbreaks should discuss treatment options with a healthcare professional.
Orchitis
Vaccination against mumps is an important way to reduce the risk of mumps-related orchitis. Prompt evaluation and treatment of urinary, reproductive, and sexually transmitted infections can help prevent complications. Practicing safer sex and seeking medical care for symptoms of infection can also reduce the risk of infections that may involve the testicles.

Risk Factors

Cold Sores
Cold sore outbreaks may be more likely during periods of physical or emotional stress, fever, illness, fatigue, or hormonal changes. Sun exposure and local irritation around the lips can also trigger recurrence. People with weakened immune systems may experience more frequent, severe, or persistent outbreaks.
Orchitis
Risk factors include infections such as mumps, urinary or reproductive tract infections, sexually transmitted infections, and conditions that increase the likelihood of infection spreading to the testicles. Lack of vaccination against mumps can increase the risk of mumps-related orchitis.
