how long after shingles rash do blisters appear
HERPES ZOSTER RASH, SHINGLES PAIN. Shingles pain starts 4 days before the rash appears. The pain will be in one limb or on one side of the trunk (chest or abdomen.) I have never seen it on two sides at once, but see dermnetnz.org, where you can see good pictures as well.ou can test yourself with a pin during these 4 days before the rash appears, to check for this condition. Compare the area of the pain with the same area on your other side. The skin in the area of the pain may have reduced sensation to a light prick, and increased pain from a firmer prick.
