My 12 year old daughter started with a cough in March. Her brother had the same thing and it seemed like whooping cough - bursts of violent coughing. It gradually changed into a more normal cough but it’s never quite gone - her brother’s did ages ago. She’s had at least one other cold in the meantime. She’s very well except for the cough which is up and down - some days worse than others. I have taken her to the GP several times who have listened to her chest and said it’s clear. It hasn’t responded to anti histamines or asthma inhalers. I just want it to go and am beginning to worry that there is something really wrong with her - I can get very anxious about health matters particularly involving the kids. Any similar stories/ thoughts?
