Welcome to Healthcare Magic
You probably have sustained injury
from the tablet lodging near the tonsil
for which you will need to seek medical help
. The Doctors would clean up the area and give you medicines to make you more comfortable and also may put you on antibiotics to help it heal. Do warm salt water gargling for relief. Avoid hot, hard or spicy food. Eat cool, soft food like yoghurt, ice cream. Consult your ENT Doctor immediately.
