Thank you! I ve had a cough for about 4 months. Left over from a couple bad viruses during the holidays. I ve been to the doctors about 4 times since the holidays (was also diagnosed with type 2 diabetes, HBP, and sleep apnea in Oct 2014), for checkups and then dealing with this cough. Regarding the cough, first they said that I was probably on the tail-end of bronchitis, or possibly allergies, so they gave Benzonate 200 mg and amoxicillin. That did work. Then next time they gave me a nebulizer treatment and sent me home with an inhaler. That didn t work. Then the 3rd time, they said it was my blood pressure pill that causes coughing and changed that. That didn t work. Yesterday I called the doctor because my coworkers are getting sick of me coughing, and they are treating for a sinus infection with 100 mg of Doxycycline Hyclate hyclate. Also, I was using a CPAP (trial period) and couldn t use. Yikes. Nothing very serious, but just wondering if it could be a deviated septum (since I have sleep apnea too). I asked to see a specialist. Do you think they are just trying to narrow it down? Worried a bit about the dosage of the new meds. What do you think?
