Pemphigoid: Symptoms, Causes, and Treatments

3. Primary Pemphigoid Symptoms

One of the most common signs - and the earliest - is the appearance of blister-like sores in the mouth. These may resemble fever blisters or cold sores. They spread to other parts of the body's mucous membranes, including the throat and genital areas.

The sores may come and go, and while painful, don't generally itch or cause scarring. They will produce a thick, crumbly crust and oozing blisters. The fluid and blisters cause the skin to separate, causing the blisters to grow in size and spread rapidly.
