Hello
Welcome in H.C.M. for your query.
I have gone through your query regarding red enlarged congested tonsils with pus is oozing out. You have enlarged node on the neck. your throat is very painful on swallowing.
You are having all these problem on left side of throat only. After returning to home you spit out thick brownish red foamy pus like discharge which is fowl smelling.
Considering these facts it appears as you are suffering from
follicular tonsillitis with
peritonsillar abscess left side. This abscess had lateron drained by it self to give rise to brownish red froathy discharge with fowl smelling.For treatment you should take-
(a) Antibiotic- With the concent of your G.P.
(b) Tab
Paracetamol.
(c) Antiseptic gargling.
(d) Plenty of liquid orally.
I hope this will help you.
Regards.
