Thanks for writing to H.C.M. for your query.
I have gone through your query regarding sore throat
and swollen tongue
for one week. You have taken benadryl but not getting much relief. this hurt you much in night hours.
Considering your symptoms it appears as you are suffering from-
(b) Allergic Oropharyngitis with Secondary infection.
To differentiate these two a thorough examination is necessary. For relief you may take-
(1) Antibiotic - preferably broad spectrum.
(2) Anti inflammatory.
(3) Anti allergic.
(5) Steam inhalation.
I hope this will help you, otherwise you should consult an ENT specialist
for examinatio and treatment.
