I was dignosed with asthma when i was around 11 but never had any trouble until earlier this year(at 26) was started on clenil modulate 200mcg 2 puffs twice a day which seemed to have kept me well controlled. However this week out of the blue ive really struggled all most constantly coughing, tight chest and oc occasionally a slight wheeze. Seen my gp today who uped my preventer to 2 puffs 4 times a day and given me a 5 day course of 30mg of prednisalone. But i seem to be getting worse can barely make it up the stairs and using my ventolin every 2-3 hours. Should the steriods started to work by now or am i just being impaitent?
