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.
Years later, the virus can become active, causing shingles. The first symptoms of shingles are unusual skin sensations. These include pain, itching and tingling. Other symptoms include confusion, fatigue, fever, headache, memory loss, an upset stomach and stomach pain. These symptoms generally occur one to five days before a painful rash appears on one side of the body or face. In most people, the rash develops on the torso and extends to the front and the back of the body. The rash forms very painful blisters that typically become scabs in seven to 10 days.
