Thanks for writing to H.C.M. for your query.
I have gone through your clinical history and I am suspecting that you are having acute pharyngitis
which is giving you feverish feeling like- headache, body ache, and severe sore throat
leading to painful deglutition resulting in excessive salivation
As far as treatment is concern first of all you should go for these investigations.-
(1) Culture and sensitivity of throat swab.
(2) Blood- CBC, ESR, Widal test
(4) Urine - R & M.
Till the reports of investigations comes you should take- Antibiotic, antipyretic-analgesic
,and as soon as reports of investigations comes the treatment may be switch over accordingly.
