I’ve been struggling to catch my breath in the last day or so. I’m having to lie down if I walk up the stairs. Just really breathless. I’m wondering whether to ring the covid-19 helpline, but I don’t have any of the standard three symptoms. On the other hand, I’ve never felt like this before and know there’s been a confirmed case at the stables that I go to. I also know someone who had Covid and they were really breathless, but also had a cough. Am I worrying unnecessarily.? I don’t want to use up precious resources.
