Abstract

Background: Shingles is one of the common skin conditions, caused by the Herpes Zoster virus. Pain in shingles is a major functional symptom that brings patients to medical specialties, especially neurology. Pain is characteristic of all three stages of zona with prominent neuropathic pain. However, pain is difficult to evaluate. There are a number of international pain scales that can be used to assess the level and nature of neuropathic pain, such as the LANSS and DN4 scores. Objective: To apply some international pain scales to assess the level and nature of neuropathic pain in shingles. Methods: We conducted a cross-sectional descriptive study of 73 patients diagnosed with shingles. We used LANSS and DN4 pain scales to assess the level and nature of neuropathic pain. Results: 70% to 90% of the patients suffering from pain were evaluated on the basis of neurological pain score (LANSS) 60.3% of patients had typical neuropathic pain (LANSS score of 21 or higher). 20% to 80% of patients were evaluated according to the Neuropathic pain set of 4 questions (DN4). 95.9% of patients had typical neuropathic pain (DN4 score of 4 or higher). Neuropathic pain and postoperative pain were significantly correlated with the age of patients. Conclusion: Shingles pain had typical properties of neuropathic pain. The higher the risk, the greater the risk of post-shingles and pain symptoms assessed after LANSS and the set DN4 questions.
