I have had a lingering cough for over 7 weeks now, it is a very deep cough that is worst in the early mornings and late evenings. I have seen my doctor twice now for it, she has given me a nasal spray in case it was post nasal drip as well as hycodan, I have used the nasal spray for over 2 weeks and tried hycodan for about a week, neither have helped. I don t know if I should go back to see the doctor or what I should do, the cough is extremely bothersome and I feel like it causes me to wheeze.
