Postherpetic neuralgia is a condition that can occur after a person has had shingles, which is caused by the reactivation of the varicella-zoster virus. This condition is characterized by persistent pain in the area where the shingles rash appeared, often described as burning, stabbing, or aching. The pain can last for months or even years after the rash has healed. The risk of developing postherpetic neuralgia increases with age, particularly in individuals over 60. Treatment options may include medications such as pain relievers, anticonvulsants, or topical treatments to help manage the discomfort and improve quality of life.
