I woke up Boxing Day with a headache, dizziness, head felt “full”, face feeling hot (but no fever). 12 days in, had a mild but odd feeling in left side of chest, can’t describe it, kind of tight as if it was being stretched. Never thought to get a covid test as the symptoms were so different to the big 3. I still don’t think it sounds anything like covid, but wish I’d got tested now!
