Hello and Welcome !
Thank you for your query.
As per your history,I would like to ask you whether you ate any fish bone by mistake,or anything similar,that you may be worried got choked in your throat.
If you say you had none of the above,then its probably nothing to be worried about!
Its just a congested pharynx,resulting in
acute pharyngitis.
if I were your doctor,I would treat you with the following
1.An antibiotic for the infection: Tab.
azithromycin 500mg PO once daily after meals., for 3 days.
2.A pain killer : tab.
paracetamol 650 mg PO twice a day after meals 3 days.
3.Salt and Luke warm water gargling thrice a day.
This definitely would bring down your symptoms.if they still persist,i recommend you to show to an
ENT specialist,for further examination and work-ups.
Thank You.
Stay healthy.
