after spending another night in hospital she is much better. her oxygen levels had dipped to 90 and she was quite rough ny time the ambulance arrived. we now have a decent plan to follow and will be reviewed in a fortnight. she is having becotide 100 morning and night, and also singulair every day, which they think will help keep her off of the prednisolone. the attacks seemed to be triggered by re-occuring viral infections, and thankfully not an allergy.
Thanks to all you lovely ladies who gave me lots of advice and support x
