Hi, ive had an ulcer for about a week now its located on my lower cheek (opposite my lower teeth incisors) and its quite big its like an oval shape and sometimes its sore and sometimes it isnt, like now for instance it isnt sore but when i poke at the bottom edge of the ulcer with my tongue it has a slight sting.
Do i have an ulcer due to stress? i have been quite stressed this past week due to school and other things.
i have been holding water in my mouth and pushing it against my ulcer is that bad for the ulcer? does it make it bigger?
ive tried salt and warm water, im not sure if it works or not because it has stopped stinging.
if it stops hurting does it mean that its healing?
and i read online that ulcers that dont heal can lead up to cancer.
