My seven year old daughter has started breathing trouble and the doctors said that she was suffering from moderate to severe Asthma and CF. She was given her first dose of IVIG for her IgG2 deficiency. When she woke up, her Peak Flow readings were very low and so I added Xenopex to her breathing to her treatment. She had mild wheezing and was coughing frequently throughout the day. She had no fever or any other symptoms that showed that there was any CF problem and the lungs seemed quite clear. She was generally better and the reading was between green and yellow zones. Is this really an asthma attack or not? I would be grateful if someone could shed some light on this matter.
