2. Puffy Blisters.
There is a good chance that you have had some blister on your skin in your life and you should be able to point out a blister when you see one. However, a blister that is associated with shingles looks a bit different than an overuse blister you may have had after working outdoors this past weekend. Blisters that are caused by shingles tend to look red due to inflammation, have tiny white blister balls, and can be wide spread. This is the most common sign of the shingles virus and if you suspect these on your skin, then it is wise to see your doctor as soon as you can so you can get treatment.
