So DD2 ,15 has just gone to gp after prolonged cough (3 weeks) it got worse 2 days ago and she couldn't stand up without being dizzy just walking up the corridor shed get really breathless and yesterday she was having chest pain. I haven't seen her this ill for ages. Shes in year 10 so i know she needs to be in school but its out of the question for tomorrow im hoping with Anti-bs shel fell better in couple of days but apparently its kind of contagious and she's also in a massive school (2200 pupils) So she might get tired even when she feels better should i keep her of for the week (Course of Anti-Bs or what Advice Please
