Not sure where to post this, so I'll try here first! My 10 year old DS has recently been diagnosed with asthma (long suspected but not a huge deal as it just presents as a horrible cough, particularly at night). He has been given a preventer inhaler to take in the morning and a blue inhaler to help if he has bad coughing/wheezing episodes. He gets bad hay-fever so has always taken an antihistamine at this time of year. It has just dawned on us that he has these 'episodes' for 24 hours after swimming lessons. Hacking cough through the night and then pretty much back to normal a day later. Is this a thing? I can't find much about it online. Should he avoid swimming lessons or can something be done about it? He has only had the preventer inhaler for a few days so we don't know if this will actually help long term or will we need to send him to school lessons with the blue inhaler? Anything else we can do???
