My best friend is going thru something very similar. She's getting frustrated because she has this annoying cough after being sick as well but she's not any closer to getting answers. She even had allergy testing, everything was negative, and has an appointment with a pulmonologist. Btw, her cough has been going on I believe for about 2 years.
I'm sorry I don't have any answers for you but I just wanted to tell you that you're not the only one out there with this issue.
