I am a 60 year old pediatric oncology nurse, 5'4'', 138 lbs, active. I am on 5 mg of amalodipine, for High blood pressure. I don't smoke and I have had GERD in the past but have not been taking any meds for it for a year or so.I developed a cough about 3 months ago, not related to any illness, upper airway, took a Z pack, did not help, went to the doctor and got an X-ray which was normal. The cough is slightly productive, more like having to clear my throat and I feel more tired then I should. I started back on 40mg prilosec 2 days ago thinking it was being caused by GERD but it has not helped. I have never had any allergies but do have post nasel drip at times. I cough more in the morning and after I eat. I am able to do my zumba classes with SOB or coughing. Any ideas?
