Why fever occurs when shingles is painful

One of the most common symptoms of shingles is pain. The pain is usually localized to the area of the body where the rash appears, and it can be intense and debilitating. When the body is fighting off an infection, it can sometimes result in a fever. The fever is a natural response by the body's immune system to help fight off the infection.

In the case of shingles, the body's immune system is trying to fight off the viral infection, which can lead to a fever. The fever is a sign that the body is mounting an immune response to the virus, and it can help to speed up the healing process. Additionally, the fever can help to activate certain immune cells that are better able to fight off the virus, which can help to reduce the severity of the infection.
