I would be grateful for any advice on my son. He has had a persistent wheezy and sometimes chesty cough since may last year. The doctors have put him on salbutemol since last may and since November he has been taking 4 puffs 4 times a day and his chest has not improved. I have taken him to casualty twice in the last week when he has had an episode where he cannot get his breath has a high respiratory rate and is turning blue. They have told me that on admission his blood oxygen level was 87%. When the doctors gave him oxygen and steriods he has improved enough to come home. However when the course of steriod tablets finishes after 3 days the symptoms return. I have been to the doctors many times and they just tell me it is a virus? I am getting desperate for answers as my once healthy happy boy cannot now walk further than 10 yards and has had to come home from playgroup on several occasions as they thought he was having an asthma attack.
