Dear Doctor, I need advice for a chronic breathing issue ongoing for 2-3 years. Every morning, I experience heavy pain, severe difficulty breathing, heavy chest congestion, and a blocked nose. I pass slippery, transparent-to-whitish, sometimes stringy mucus that feels impossible to clear completely. This used to last 1-2 hours, but over the past few days, it has worsened and now lasts 3-4 hours before returning to normal for the rest of the day. I also have long-standing sneezing fits (at least 3 sneezes in a row), triggered by dust/blankets and occasionally occurring randomly. I do not have sinus pain or headaches. I live in a high-pollution, heavy-traffic area and tend to feel cold easily, preferring to keep my torso covered. Could this be allergic asthma, severe allergic rhinitis, or pollution-related airway inflammation? Please advise on diagnostic tests, appropriate prescription treatments, and management strategies.
