Canker sore // healing process?

[ehoz]

a week ago today - i began having on/off again pain in the back right of my mouth. a couple days went by, and the pain increased and spread to my jaw and lymph node. i couldn’t talk or eat without being in extreme pain. on tuesday- i went to urgent care and she diagnosed me with an ulcer and gave me numbing medication and amoxicillin just in case it was an infection of sorts. i’ve been taking the amoxi as directed and haven’t felt the need to use the numbing meds too much since friday. it’s now sunday and i’m just panicking about this entire thing. the inflammation and pain have gone down severely but i’m just scared idk. is it normal to look like this? it’s a literal hole. i also noticed my Linea alba is starting to get bumpy.
