There are three main stages of shingles. Their duration is somewhat predictable, but the time spent in each stage along with the symptom severity can vary from person to person.

Symptoms

In addition to pain and a rash, other symptoms of shingles may include:

PHN is usually diagnosed if pain, burning, tingling, or other symptoms continue 3 months or so after the rash has disappeared.

Treatments
