Patient: I have a constant post nasal drip now for a couple of years. I am from Puerto Rico and I moved to Missouri 2 years ago, then I moved to Colorado. I have been in Colorado now for a whole year. Ever since I moved to colorado I think my post nasal drip has been worse and I alse have trouble breathing. I have had heart tests and blood pressure tests. Everything is fine. I need to get rid of this post nasal drip but I dont know what else to do. I have taken medication and it just keeps coming back.
