I am sorry you are having swelling under your tongue and sore throat.
you could be having a viral or bacterial throat infection like strep throat.
you should see a doctor at the hospital or A&E department and get a throat culture to look for infection.
you might need a course of antibiotics if you are found to have an infection.
do you have any fever or pain in your throat?
