Where on the body is shingles deadly?

The face and eyes.

Shingles is a painful skin rash caused by the varicella-zoster virus, which is the same virus that causes chickenpox. The rash usually appears as a band of blisters on one side of the body. In most cases, shingles is not life-threatening and will clear up on its own in 2-4 weeks. However, it can be dangerous if it affects the face and eyes.

If the shingles rash spreads to the face, it can cause inflammation of the eye (keratitis) and even blindness. In some cases, shingles can also lead to facial paralysis.

If you have shingles and the rash is on your face, it is important to see a doctor right away. They can prescribe antiviral medications to help speed up the healing process and reduce the risk of complications.
