If the doctor says so. Sounds sort of like Post-Nasal drip to me, but your doctor probably has more sensitive instruments and a good image of the inside of your throat, something that I don't have, and therefore his opinion takes precedence.
My friends all ditched me because their overly self-conscious. I basically sat in the pool trying handstands like a loser, and then my leg cramped up so I couldn't even do that. Then while walking home my leg cramp prevented me from walking fast so I took half an hour to get home instead of twenty and I had to walk bare foot because before I had walked too fast and my flip flops dug into my foot. I think I have blisters.
