For about the last week or so, I’ve noticed I have a kind of wheezing/rumble in my chest. It’s most noticeable first thing in the morning, but does sometimes reappear at other times. I have a bit of a cough but nothing dramatic. No other symptoms that I can discern: no shortness of breath, pain, dizziness etc. When I exercise I don’t notice any difference in performance. Is this worth making a GP appointment for, if it persists? What could it be? I feel like if it was a chest infection or similar, I’d have more symptoms and more generally feel unwell in myself. But I’m mostly ok, occasionally coughing, but with this wheezy/rumbly sound.
