I've had coronavirus for a few days and so far it's been quite mild. My symptoms have been lessening since Wednesday and yesterday I hardly had any, so I thought I had got to the end of it. But now I'm having this pain in my back - my lungs, I imagine. It's mostly tolerable but it can feel quite painful at times. I also have increased heartbeat and a worried feeling that I'm definitely not out of it yet.
Any advice?
