I'm having a tough time with my breathingI struggle to take deep breaths sometimes, and I've been relying on breathing through my mouth for the past four months. I visited a pulmonologist who had me take a chest X-ray, but it came back normal. He prescribed Razo D Tab 20mg for three weeks. Things seemed better during the first week, but by the second week, the breathing issues returned. Other than this, I'm eating well and sleeping properly, but every now and then, when the breathing gets difficult, I feel fatigued. There's no other issue apart from this. However, due to the current lockdown, I can't visit a clinic for a follow-up. What should I do next? Any suggestions on managing this?
