What is shingles?
Shingles occurs when the virus that causes chickenpox becomes active again.
Symptoms, causes and assessment
It commonly causes a painful, blistering rash on one side of the body; pain can precede rash. Other conditions may look similar. Some people have lingering nerve pain after the skin heals.
Care and when to seek help
Early medical advice can matter for treatment. Rash near the eye, vision changes or widespread severe illness warrants prompt care. Vaccination may be appropriate under current recommendations.
