I've been dealing with allergic asthma for 20 years, and it usually flares up around March every year. I've been using Seretide Accuhaler 500/50mcg for the past 15 years. Lately, though, I've been having trouble breathing and feeling tightness in my chest. My X-ray shows haziness in the left lower lung zone and prominent vascular markings. What could this mean? Is it related to my asthma or something else? Please help.

The haziness in your left lower lung zone and prominent vascular markings could indicate mild inflammation or fluid retention in the lungs, which may be related to your asthma or a respiratory infection. It's important to consult your doctor for further evaluation and treatment adjustments to manage your breathing difficulties and chest tightness.
