I had a bad reaction to a personal lubricant that got into my mouth. It's been a few days, and now I have a smooth red patch on the roof of my mouth, as well as some irritation on my lips. I don't have any swelling, although I did the first days. That same day, I also happened to burn the inside of my mouth with a hot drink. What do you think it is, and what should I do? Is there anything I could take?
