6. Infection
Infection can cause you to get blisters. Some infections can cause blisters to include cold sores, chickenpox, and shingles. When you have these infections, blisters can’t be prevented until the infection clears. When you’re dealing with an infection you have to be careful to not spread because chickenpox and cold sores are contagious. You have to practice good hygiene when you have these infections.
With chickenpox, you will have blisters all over your body, including your face and neck. You can use ointments to dry up the blisters to prevent you from trying to pop them. With chickenpox it causes your skin to itch a lot. Once you scratch the skin, the blister will drain out and spread on another part of the body, especially if you don’t clean the area afterward. Sometimes with an infection, the blisters will drain out blood, especially if you scratch it hard enough.
