Shingles starts with some pain or tingling on the part of the body where the rash will appear. This can happen 1-5 days before the rash appears. Next, a raised blistery rash appears. Over the next 7-10 days the blisters break open, leak fluid and crust over. It may take more than 4 weeks for these blisters to fully heal. Keep the rash covered until it is fully crusted over to prevent transmission.
