The most common symptom of shingles is pain - a constant dull, burning, or gnawing pain, or sharp, stabbing pains that come and go. Other common symptoms include tender skin and a blistering rash.
Shingles usually lasts for a few weeks. Usually, the first symptom is pain or numbness. A few days later, blisters appear. The blisters last for several days and then usually scab over.
