Shinglesandpoison ivycan both cause a blistering rash that can look very similar, so you may wonder how to tell the difference. Even though the rashes look much the same, their causes, treatments, and prevention are different.
Although shingles and contact dermatitis from poison ivy both lead to small blisters, they are different in that shingles is very painful and the rash is limited to one part of the body. In contrast, the rash of poison ivy is incredibly itchy, with less pain, and can be found anywhere on the body.
This article discusses shingles and poison ivy rashes, focusing on symptoms and key differences.
