世界镇痛日：“记忆痛”需要规范治疗

Core Insights - The article discusses "memory pain," a condition that can arise after the healing of shingles, known as postherpetic neuralgia (PHN) [1][2][3] Group 1: Understanding Memory Pain - Memory pain can begin 1 to 3 months after shingles has healed, despite the virus being cleared by the immune system [1] - The damage to the nerves caused by shingles leads the brain to misinterpret normal sensations as pain, resulting in various pain types such as sharp, burning, and allodynia [1] Group 2: Risk Factors and Prevention - Individuals over 60 years old, those with severe acute rashes, and those experiencing intense pain during the acute phase are at higher risk for developing PHN [1] - The optimal time to prevent PHN is during the acute phase of shingles, where early and adequate antiviral treatment within 72 hours is crucial [1][2] Group 3: Treatment Approaches - For chronic pain, a combination of oral medications like gabapentin and pregabalin, as well as topical treatments like lidocaine patches, can be effective [2] - If medication is insufficient, minimally invasive interventions such as nerve block therapy can be employed to directly target the damaged nerves [2]
