Neuralgia is a type of pain that occurs along the path of a nerve. It is often described as sharp, stabbing, or burning and can be triggered by various factors, including injury, infection, or underlying medical conditions. Common types of neuralgia include trigeminal neuralgia, which affects the face, and postherpetic neuralgia, which can occur after a shingles infection. The pain associated with neuralgia can be severe and may interfere with daily activities. Treatment options often include medications such as anticonvulsants or pain relievers, and in some cases, physical therapy or nerve blocks may be recommended to help manage symptoms.
