Do you think I have this or is it something else?

[yopopo]

Saturday I started getting aching muscles in my neck (as if I had slept funny )
I felt slightly out of breath
Yesterday I was out of breath when moving around and talking I had to take deep breaths through my mouth.
My chest is sore but it's not a dry cough I'm just coughing up phlegm to clear my chest
My head feels a bit fuzzy
I don't think I have a temp but I don't have a thermometer.
It's the breathless thing worrying me.
Even standing up I feel out of breath and talking is making me out of breath.
I don't want to be a drama queen and ring 111
I don't feel ill or anything.

Have you tried this:

111.nhs.uk/covid-19

Hope you feel better soon

Breathlessness and tiredness are symptoms. Cough not necessarily dry. I am not a doctor, but I am on day 7 of probable CV19. Do use the 111 symptom checker as above. Hope you feel better soon.
