Hi, I wondered if anyone had experience of this... My son is 4 years old and been coughing a lot, almost constant at night. He is usually fit and healthy. We visited the doctor last week and he presumed that it was asthma and gave him a blue inhaler. However this did nothing to help. So i took him back this week and the doctor said perhaps reflux so gave me some medication for that. He's been taking it for a couple of nights and it seems to have calmed the cough down. Not completely but mostly. So assuming it is reflux, is this a permanent thing? Does anyone have experience of anything like this? TIA.
