Please tell me, could vomiting a lot cause cold sore and canker sore ?
A doctor has provided 1 answer
Possible: Vomiting can make your mouth sore because of the acids. You may have more canker sores because you are sick and your immune system is compromised. Cold sores are caused by herpes simplex.
