My asthma flared up three weeks ago but I don't know what the trigger was. Having spent a week on 40 mgs of prednisolone daily followed by a week on antibiotics and reducing the dose of prednisolone by one for a week I am still coughing at night, my throat is sore and I have very little energy. Is this normal? Should I go back to the GP? I hated taking the prednisolone as it made me feel spaced out and,as I am diabetic, it put my blood sugar up and this was difficult to manage! I am not using the reliever during the day now but feel tired in the afternoon.
