You really shouldn’t Google, especially with health anxiety.

The body is ever changing and there are many things that go on in the mouth that cause cold sores, irritations, swelling, inflammation. Your body is constantly working for you.

Worrying adds undue stress/anxiety which can pro long bodily healing.

I would seek help for health anxiety. Your PCP probably would like to tell you this, but can’t due to liability issues.

Many people whom come to health forums like this, suffer from health anxiety and reassurance seek.

The worst cycle you can get into is speaking worn strangers on forums whom encourage you to see more doctors.

Leave this up to you and your PCP to discuss. Not strangers, whom probably also reassurance seek.
