There has been an exponential increase in catheter ablation procedures for the treatment of cardiac arrhythmias over the last decade.
Shingles blisters usually scab over in 7-10 days and disappear completely in two to four weeks. In most healthy people, the blisters leave no scars, and the pain and itching go away after a few weeks or months.
After a few days of the above symptoms, a red rash appears where there was itching or tingling, usually on one side of the body. Blisters can form and crust over, although not everyone with shingles develops such a severe rash. A shingles rash can last anywhere from 1 to 14 days, although the blisters can take longer to heal. Shingles can't be cured, but antiviral medications and steroids can shorten its duration. Pain relievers, anti-itch creams, compresses and cool baths can ease rash itching and pain.
