Classic symptoms of shingles are painful blisters in a band along a nerve distribution on one side of the body. These blisters usually break open and ooze fluid. This may last about five to seven days. The pain in the area of the rash can be intense as the nerve is irritated. The individual is contagious to spread the virus infection when blisters are forming and until all of the blisters have crusted over. The rash may heal in about two to four weeks, and some skin areas may scar.
