My physician told me due to it's location and appearance did not feel like i was having an OB and said there was no real need for a culture to be done. Simply thought it was a result of the hot food i ate. No real treatment other than time.
Do you have an existing hsv1 infection, or are you concerned this is a new infection?
I can't tell you if you are having an ob or it's a bad burn, but in an existing infection, it's not common to get outbreaks in your mouth. If you think this may be a new infection, you should see your doctor.
Really, though, in either case, you should see your doc. That looks like a nasty burn if it's a burn. If it's a burn, though, I'd be surprised if your tongue wasn't also burned.
Can you get to an urgent care? If they think it's hsv1, make them do a culture on it, especially if this is a new infection for you. Don't let them just guess.
Let us know what the doctor says.
