Obviously can't go to the Gp as not open. He's had a bad cough all week, no temp or other signs of a cold. We've been on a caravan holiday this week though and the weather has been very cold and windy especially at night which is what has bought on his cough. Cough is always his worst asthma symptom at night. We usually always have a spare inhaler but because of the extra use this week it's run out. He's coughing non stop now and I can hear a bit of wheeze, is the best option our local minor injuries?
