I'm feeling a bit anxious because I've been having shortness of breath ever since I got my first dose of Covaxin. I did see a doctor, and they suggested I take Broclear and get an X-ray. I got the X-ray results back, and they were mostly normal except for this note about increased bronchovascular markings in both lung fields. Should I be worried about this? What does it mean, and what steps should I take next?
