Bubble/sore in mouth

Rachel • “If you can dream it, you can do it”

I have this little bubble/sore in my mouth on the top left side of the lining of my upper lip and it’s a bit sore to touch and I don’t notice it unless I talk or play with it with my tongue. Its hard to tell from the pic but it looks like a clear bubble/ball. I gave my boyfriend oral last night and he cummed in my mouth but I didn’t swallow, does anyone get this have oral and what can I do to get rid of it? Sorry for the weird pics 😅
