[|Human|] I woke up with a very tight jaw, limited motion, I thought from grinding in my sleep, and the next day a canker sore.  I just had surgery to remove a benign lump (last week) Wondering if there is any connection....  havent called my doc yet.  Just thought today, how odd....
[|AI|]  Thanks for your query. I have gone through your query. The soreness or ulcer could be an authors ulcer. The most common cause is stress or post surgical(removal of lump) or nutritional deficiency. Nothing to be panic, consult an oral physician and get it evaluated.Meanwhile, you can take symptomatic treatment like topical anesthetic like 2% lidocaine gel. Apply 3-4times daily. Consume nutritious food. Lead a stress-free life. I hope my answer will help you. Take care
