Hello, Welcome to the Pain Managment Forum. I am sorry you are suffering with mouth ulcers
. They can be painful. My grandmother use to tell me to put salt on the...ouch!!
Mouth ulcers, sometimes called canker sores, are a common affliction. Often they are simply caused by trauma and heal quickly on their own. The recurrent, bothersome form is known as recurrent aphthous stomatitis or simply aphthous ulcers.
Cause is unknown, though it is believed to be some sort of immune mediated condition.
