Hi my 10 year old son was very badly vomiting on Sunday night today he’s been coughing all morning. Iv kept him off school as he has to stay off for 48 hours because he was sick. I have had to take unpaid leave from work. Do I need to gauge his coughing? He’s no other symptoms only a sore back but that could be because he was sick. Or just order a test right now. I haven’t had to deal with this before so unsure thanks
