I'm really worried about my allergic asthma that's been going on for 20 years now. Every March, it seems to get worse, and I've been using the Seretide Accuhaler 50050mcg for the past 15 years. Recently, I've been experiencing difficulty in breathing and a tight feeling in my chest. I just got my chest X-ray done, and it showed haziness in the left lower lung zone with prominent vascular markings. Could you help me understand what this means? I'm really concerned.

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.
