Bullous pemphigoid is a rare skin condition that causes large, fluid-filled blisters. It mainly affects older adults and is linked to the immune system mistakenly attacking healthy skin tissue.
Although it can look serious, it is not contagious and can be managed with proper treatment.

In rare cases:
Small blisters or sores may form in the mouth
The condition often starts with itching and rash before progressing to visible blisters.
