I've had this stubborn dry cough for about 15 days now. It all started with a cold and cough, and I took some antibiotics and chest cold tablets for a few days back then. The cold cleared up, but this cough just won't go away. It's mostly at night before I sleep, but somehow it doesn't bother me when I'm actually asleep. The coughing makes it hard to breathe and sometimes I feel like my heart's racing. I even get these shivering vibrations in my upper body and hands. I already spoke to a general physician and got a bunch of medications like montelukast sodium, levocetirizine hydrochloride, methylprednisolone, and cefpodoxime proxetil potassium clavulanate. I'm on my second day of this prescription, and then I read online that some of these are for asthma. Really curious and a bit worried about what this could be, and if it's got to do with my lungs or heart. Any advice on what's going on and how to find out more?
