I'm really concerned about my wife. She's 32, doesn't smoke, and has had this persistent dry cough for almost a month now. It's like clockworkevery 30 minutes, and the coughing lasts about 4 to 5 seconds. We've already seen a pulmonary specialist. The first time, he prescribed some antibiotics, and then after two weeks, they did an X-ray, which came back normal. The doctor switched up the meds after that. It got slightly better for a bit, but for the last 4 days, the cough has returned, especially when she's lying down. I'm attaching the last prescription we received for reference. Right now, she's only using an inhaler twice a day as the rest of the medication course has ended. Could you give us any advice on what might be happening or what we should do next?
