Shingles, a viral infection of the nerve roots caused by the chickenpox virus, can sometimes lead to a painful complication called post-herpetic neuralgia. Sometimes, a physical stress like cold or sunburn can bring on an attack. Even clothing touching the skin or a cool breeze can cause excruciating pain.
Shingles (herpes zoster) occurs when the dormant chickenpox virus (varicella-zoster) is reactivated in your nerve tissues. Early signs of shingles include tingling and localized pain. Most, but not all, people with shingles develop a blistering rash. Typically, the shingles rash lasts two to four weeks, and most people make a complete recovery. Doctors are often able to quickly diagnose shingles from the appearance of the rash.
