Hello, I recently injured myself by busting my bottom lip, and I now have a large ulcer on the inside of the lip. It's very difficult to eat, and extremely sensitive. My lips have now become very sore, swollen and chapped. They're so painfully dry that it hurts to talk. I also feel very sick, like I could vomit. Is there anything I can do? Is everything, the sickness, ulcer and chapped lips related? Thank you.
