My three year old son has a severe egg allergy and was diagnosed with asthma at 12 months, I have seen a number of doctors, nurses and peadiatricians, he has recently been given a new green inhaler (he already has the blue and brown) and has been using it for about 6 weeks, but I have seen no significant improvement, I have singulair tablets but his peadiatrician did not want me to give him these yet, has anyone got any advice? I would like to send him privately, does anyone know any very good asthma specialists/clinics?
