I did a stupid thing and ate such hot oatmeal. It was so hot that in the microwave it was boiling over. I just wasn't thinking. This was yesterday. Anyhow after it happened I applied cool wash clothes and now today have been putting neosporin lip treatment and chapstick. It has formed a bubble on my outside of lip like a cold sore. I am assuming like a filled blister.Is there anything else I should apply or being doing? It looks like it needs to pop and is so gross. Thanks
