Ds is 8, over 4 weeks ago caught the usual virus, high temperature and snotty with a chesty cough. After a few days the temp had gone but still wasn't 100% but wasn't concerned as such. A lot has happened over the last month (been in and out of hosp with his sibling) and today sitting with him I can hear his chest, like a cat purr? I guess that's all the catarrh? He's got a chesty cough still but he isn't ill. He's asthmatic but isn't wheezy or short of breath etc. Doctors obviously aren't open until next week and I don't want to block up emergency appointments but he won't get apt for few weeks. Would you be concerned to be like this over a month later?
