I’ve posted a similar thing OP think it could have been circulating a while - much longer than we think anyway. But also posted re something we’ve all had.
So early mid Jan DC (toddler) poorly, horrible cough, gungey eyes and when we got him to GP really sore throat, temp spiking to 40.5, but coming down with calpol on an off for over a week. 2 weeks after he started my Dad comes down with it, says he feels fluey (shivers/achey) sore throat and a cough, cough ramps up over the course of a week, really dry, barking - not chesty. My Dad is one those that just gets on but said he felt so miserable for 2 weeks in bed for a lot of days, still crap 3rd wk. 5 weeks on better but still the occasional cough. Same time DH starts with a dry cough, feels like he’s going to come down with something but comes and goes for 10 days then feels better.
3 weeks after DC started I started. Bit of a cough - tickly, headache, day 2 Achey/fluey 38.2 temp - horrendously shit, cough progressed massively, never had a cough like it, and in my 20’s I smoked and always got a bad cough with a cold but this was dry, not at all productive and was relentless.
I wouldn’t say I was quite as bad as when I had flu ache wise, but for a full 7 days couldn’t get out of bed really, also the sore throat seemed to last for ages, wk 2 v weak and had to request to work from home - couldn’t have gone in. Week 3 knackered from it and still coughing but a bit better, 4th wk coughing still but less, but now could feel it on my chest front and back - that crackly feeling. I’m in the 5th wk now and coughing less again but chest still bad went to GP and they said there is a bit of crackling - asked travel history but didn’t want to swab because no recent travel. Have given me antibiotics. To go back after biotics.,Never had anything like it.
DB also got it, same symptoms as me Dad and my DC but just not quite as bad or for as long. DM fine.
I will say that apart from feeling it round my sinuses none of us had sneezing or a runny nose.
To me they’re basically the symptoms that are on NHS Choices. And the fact I’m fit and a none smoker in my late 30’s and my chest is still uncomfortable makes me wonder.
