Usually, a swollen tougue
is associated with allergy but your
strep throat is persistant. It may have been due to so many antibiotics or a reaction to one of them. I'm glad you didn't have thrush, I figured since you had strep throat, a classic sign is pus on the tonsils or on the sides of the throat. Usually, thrush is on the tongue. Anyway, I hope you get this resolved verys soon.
