A herpetic whitlow, or whitlow finger, is an abscess of the end of the finger caused by infection with the herpes simplex virus (the "cold sore virus").
It usually affects the fleshy area of the fingertip. There are two types of herpes simplex virus (HSV), type 1 and type 2. Both HSV-1 and HSV-2 can cause a herpetic whitlow.
A herpetic whitlow can develop as a secondary infection if you already have a cold sore or genital herpes and you touch the sore area of skin, transferring the virus from your mouth or genitals to your finger.
It can also develop if you touch the sore or blister of another infected person. You're at greater risk of becoming infected if you have a weakened immune system.
SIGNS AND SYMPTOMS
The fingertip suddenly becomes red, swollen and extremely painful
Small white blisters develop underneath the skin of the finger, which may break to release fluid, eventually crusting over
