My mother has a really bad cough, she says it is because of her allergies, or her blood pressure medicine. I am really worried and I just want to make sure she's being healthy. The cough makes me cringe, it sounds very dry, and I would perceive it as a smokers cough, but I don't know what to call it since I don't hang around smokers. She always stops coughing after a while, less in the mornings and somewhat more at night, so, is she OK? She went to a doctor, and I just want to know if what she told me is true.
