Presence of yellow spot with red ring in the tonsils suggests that you might be having Acute Tonsillitis
Management consists of:
1. Gargle with warm salt water to relieve throat pain.
2. Analgesics like paracetamol
3. Antibiotics like amoxicillin
to remove the causative organism of Tonsillitis.
So...it will be better to meet an ENT specialist
& start the treatment.
There is no need to worry...you will be perfectly fine.
Wishing you a speedy recovery.
Thanks & take care
