I'm dealing with this persistent dry cough that's just not going away, and it's been happening every couple of months. I've seen a few doctors, and none of the medicines they suggested have relieved it. They've mentioned it might be bronchitis, but I'm not so sure anymore since nothing seems to be helping. I've tried antibiotics, various syrups like Ascoril and Brozodex, inhalers like Seretide 250 and Foracort, and tablets like LCZ Plus and Gramocef 200 mg, but it's like I'm not making any progress. There's no sputum coming out, and it's causing a lot of discomfort in my chest. It's gotten to the point where I'm not even sleeping well at night. I'm really worried and could use some guidance on what else I might try. Any advice?
