Do I need to have a doctor look at my blister?

Blisters generally do not need a healthcare provider to look at them. There are no tests or diagnostics for blisters.

If a burn or frostbite caused your blisters, a healthcare provider may need to treat the underlying cause. You may also need to see your provider if a blister shows signs of infection, such as:

• Pus (yellowish or greenish discharge).
• Hot or painful area around the blister.
• Red streaks around the blister.
