I have multiple canker sores in my mouth some on my front gum have left scars those are feeling better but i also have one on my uvula and on one of my tonsils i also have a sore throat and draining nose as well as inflamed tonsils?

It's obvious that you're dealing with more than canker sores in view of the apparent tonsillitis. This requires a rapid throat culture to check for strep which,if present,requires oral antibiotics. It may all be a viral infection,though. I doubt infectious mononucleosis at this time. See your physician and get tested. Treatment advice will also be given to relieve mouth sores and nasal congestion
