As title. Around my adam's apple.

When I push my throat, just under my chin, I can feel a slight
sensation.

It's not so noticable when I eat or drink.

Very hard to describe! However, it has me worried. I've had it for
about five days.
I used to smoke for about 3/4 years but gave them up about 10yrs ago.
I'm in good health otherwise.

Shoud I go to the doctor or is there something I can pick up at the
drugstore?

What could this be? What is the best/worst scenarieo?

Thanks in advance.
