Dear, As per the history you have given and the clinical findings you may be suffering with tonsillitis. smoking may not be the culprit but it is bad oral hygine . try to do the warm saline gargles after food intake. you can start the antibiotic if it doesnt go in few days along with antibiotic. I would suggest you to consult the Specialist if you don’t get relief as on examination the findings may be different and line of treatment may have to be changed.
