Hi . I am Dr Sonia S V an ENT Surgeon . A fish bone can be stuck in your throat or it may have grazed the delicate lining of your throat.The only way to be sure is to visit your local ENT Specialist
.In the meantime you can gragle with salt water.If pain develops or fever
develops or swelling feeling increases visit your ENT doctor earlier.
All the best
Dr Sonia S V
Consultant ENT and Head and Neck Surgery
