Do you pop a fever blister on your lip that has fluid?

Do not pop a fever blister on your lip that has fluid. Popping a fever blister can lead to infection, scarring, and increased risk of spreading the virus to other parts of your body. The best way to treat a fever blister is to leave it alone and allow it to heal naturally. There are various over-the-counter and prescription medications available that can help reduce pain, itching, and inflammation associated with fever blisters. If you are experiencing severe symptoms, such as difficulty swallowing or talking, or if you have a weakened immune system, you should consult with your healthcare provider.
