[|Human|] i cut the inside of my mouth with my toothbrush on accident last week and it resulted in a pretty nasty and uncomfortable canker sore. Now that it has been a few days since the sore developed, the underside of my jaw on the same side is very tender, and I can feel a small lump when I tilt my head a certain way. Is the lump something I need to be worried about or is it just there because of the canker sore?
[|AI|]  Hello, Thanks to share your query with us. On considering your description it seems that you had an injury because of tooth brush tuft, and it has developed in an ulcer. As per the lump and tenderness you described can be because of the ulcer. If it is traumatic ulcer it would heal by itself, if you are having discomfort you can use local anesthetic like Colonel.Also, you should maintain good oral hygiene. In case. The ulcer is not healing for more than 15 days please consult with the dentist or physician. Take care. Thank you.
