I think you should! Even if it's nothing, at least you took the safest path! I would totally go in your place! I hope you get better soon =)
I started out the same way, went to the doctor, got some antibiotics, but they don't seem to be helping. Cough medicine isn't working anymore either. Been two weeks for me as well. I will probably go back to the doctor tomorrow.
I would definitely go to the doctor if I were you.
idk where u live but did you move recently?
