What is the difference between adverse reaction, side effect and an allergy?

A doctor has provided 1 answer

Different reaction: Assuming this is about medications: and adverse side effect would be a reaction that occurs after taking a medication regardless of the cause of the reaction. An allergy is a specific type of adr, that is allergy antibody mediated can be expected to occur everytime the medication is taken.

A member asked:

When I consume certain food/drinks, the back of my throat only on one side (the tonsil area) feels inflamed and a bit swollen. I have no other reaction, it goes away after a couple hours. Is this a form of allergy? Why is it always on just one side?
