The first sign of shingles is usually pain, which can be severe. After a few days, a person with shingles may develop a rash and fluid-filled blisters. Shingles can also cause burning, numbness, itching, and sensitivity to touch. It usually affects only one area of the body at a time, often appearing as a stripe of blisters on one side of the torso. People with shingles are contagious to those who have not had chickenpox or the chickenpox vaccine, but they are only contagious while they have open sores. If somebody catches the virus from a person with shingles, they will develop chickenpox, not shingles.
