child with repeated ear infection

Since birth my son has had 4-5 ear infections resulting ruptured ear/ drainage. Before 1 yrs. he had repeated episodes of bronchiolitis but with the help of a homeopath was stabalized with C. Carb and Chamomila. After 2 yrs. he stopped with lower respiratory infections and now only has upper rep. infections with ear. He suffers from apnea, mouth breathing, repetitive right ear infections and excema. An ENT specialist told us that his adnoids are not abnormaly large and suspects allergy as our family has many allergic members. Neither Zyrtec, Claritin, Zasten or any of the other antihistimines seem to help and i have put him on Sulphur for 3 days and then switched to Lycopodium once his ear began to drain. Any suggestions? (sulphur seems the most indicative of his general symptoms, but does not seem to have a great effect overall. He was put on Sulphur as a baby without much effect either, then switched to Arsenicum and later to Lycopodium)
