But it can also lead to chronic nerve pain. The German Brain Foundation points this out.
About one in ten patients is affected by long-term burning pain (called postherpetic neuralgia) in the upper body, arms, legs or face. Sometimes they also occur without the blisters on the skin that are typical of shingles. The disease can then be detected by antibodies to the virus in the blood.
