How to Get Rid of Herpes on Arm

Herpes on Arm Herpes simplex caused by herpes simplex virus (HSV) can affect any body area including face, mouth, eyes, nose, hands, brain and genitals and the infection is categorized accordingly. Herpes on arm is a condition that results from herpetic whitlow. Among two most common variants of herpes virus, HSV-1 is responsible for causing herpes on arm. This infection usually results from the herpes infection on other body parts. Herpes whitlow is characterized by red, painful blisters on the arms and fingers.

Causes of Herpes on Arm

Herpes infection of mouth and genitals is most commonly found. But, herpes on arm, back or legs is less frequent. It happens in the immunocompromised people due to spread of virus from other affected body parts, as this infection is highly contagious. If the person has oral herpes, the virus may spread due to touching the blisters and not maintaining the hygienic conditions. The virus enters the body and remains in an inactive form. When the immune system weakens due to illness, stress or poor nutrition, the virus becomes active and causes primary outbreaks. It results in itchy, painful rash on the arm. Health care professionals are at a greater risk of getting this infection, as they are constantly exposed to the lesions and body fluids of an infected person.

Herpetic whitlow may arise following the chickenpox infection caused by varicella zoster virus (VZV). This virus may remain in the body in the dormant form and may cause herpes infection, when it activates.

Patient may notice swollen lymph nodes in the elbow or in the underarm area. Usually, the blisters scab within 3 weeks, leaving no scars in most cases. Since the virus remains in the latent form, there are chances of recurrent infection, which is triggered by certain factors like trauma to affected area, emotional or physical stress, sun exposure and hormonal changes. However, recurrent infection causes milder symptoms and last for short period.
