Possible symptoms of coronavirus?

I live in Scotland and have made phone calls and searched the NHS website without success. My mum has been self-isolating for 3 weeks and was diagnosed with coronavirus. I started experiencing breathing abnormalities on 15th April. I'm wheezing a bit and when I take deep breaths, I have mild pain in my chest. I couldn't find the answer anywhere else, so I'm trying Yahoo. Now that 7 days have passed since I started getting mild symptoms, is it all right for me to go back to work as a carer for the elderly and go to the supermarket even if my breathing isn't quite right? I wouldn't say I have shortness of breath but I'm wondering if I would go back to work only when my symptoms have stopped.
