Wtf is this on my lip??

[Mrspimplepopper]

Appeared about a week ago, looks like a bubble or blister. Totally painless. I am prone to mouth ulcers but I've never had anything like this.

Anyone have any idea please? Its really manky

Mucocele. Have a google. It's a minor salivary gland that's stopped working properly.

I’ve had ulcers that started out looking like that.

Mrsmorton I'm off to google thankyou
