I'm awaiting PCR result (requested by work - NHS). Have had sore throat, headache and (non-continuous) cough for a few days. Very tired.
I've just woken up and realised I can feel a purring sensation in my upper chest. Not constant but very regular, few seconds at a time. It's not in time with either my inhale or exhale. My chest isn't sore (apart from when I'm coughing when it burns a bit). Crackling would be too severe a description.
Am 41, fit and well, have never smoked and have never had any sort of chest infection or respiratory condition.
Is this a thing with coughs and/or Covid?
