We have seen the gp three times in the last two weeks. the first time he was diagnosed with a chest infection and was prescribed anitbiotics because he had been unwell with a cough, cold and low-grade fever. The last time however the child was diagnosed with asthma and commenced on Singulair (Montelukast), 1 tablet daily the the whole family has been sick with a persistent cough and three of us still have it but the five year old is the worst as she coughs and coughs and coughs until she vomits.
