Get dizzy when I cough. Cough real hard like a bronchial cough. BP 182/90 Resp. 16 Pulse 68. Got a cold In the end of Oct. Still have cough. Had Resp infection , sinus infection and a touch of pneumonia. Was on Arithromiacyn and continued to have green mucus til a week ago. I take 50 mg Atenonlol and 10 mg lisinopril every day and we are unable to get BP down, could this be a cardiac problem? My cholesterol is 140 and I have gained 20 lbs since June. I am disabled with back problems and neuoropathy. I also take 1200mg of Gabapentin and Naproxen 500mg x2 everyday.
