How do I know if my skin rash is from lupus or just an allergy?

Lupus rashes are often different from allergy rashes. Lupus rashes may appear as a butterfly shape on the face, while allergy rashes can be itchy and vary in appearance. See below to understand more.

Explanation

When trying to figure out if a rash is from lupus or an allergy, it helps to look at how the rash looks and feels. Lupus rashes often appear as a butterfly shape across the cheeks and nose. They can be red and may not itch. Sometimes, lupus can cause other skin changes too.

Allergy rashes, on the other hand, can be different. They might be itchy and can appear anywhere on the body. They can look like hives or red patches.

It's important to remember that both lupus and allergies can cause skin problems. Sometimes, people with lupus can also have allergies. If you have a rash and are not sure what it is, a doctor can help figure it out. They might ask about other symptoms you have and do some tests to help decide what is causing the rash.
