Presence of yellowish white spots
over throat indicate that you might be having Pharyngitis
1. Gargle with warm salt water to relieve throat pain.
2. Analgesics like paracetamol
3. Antibiotics like Amoxicillin
(to be started depending upon the result of culture sensitivity report of throat swab).
4. Antihistamine preparations can also be used to provide symptomatic relief.
So...it will be better to consult an ENT specialist
for further management.
Meanwhile...avoid cold food & drinks, maintain adequate hydration & take soft, non-spicy foods.
Wishing a good health & speedy recovery.
Thanks & take care.
