It's an odd bug
He is exhausted, is being sick but intermittently more as a reaction to a temperature or shaking & he is sweating (it's not hot here)
He looks awful, no diarrhoea but going to the loo often, feeling queasy
He doesn't really get 'tummy bugs' and the few times he has had one (over the last 20 yrs or so) he has been fine within 6-10 hours - this has been going on since Sunday evening.
He has chronic asthma & lung disease (Bronchiectasis) so takes a lot of drugs and I'm a bit worried but I'm not sure why, something I can't quite put my finger on
