I'm really concerned because I've been having this shortness of breath and dry cough for like a year and a half now. It's really unsettling and I just cant figure out whats going on. I dont smoke or drink, and I stick to a vegetarian diet, hoping that helps. Can you help me understand what might be causing these symptoms and what I should do next?
