hello doctor..my 7 month old have cold from nearly a month. yesterday blood test has been taken which says he has some allergy..because of that allergy, wheezing was also there. a month medication along with a spacer and inhalers has been suggested. how long can we treat this and how do I know what triggered allergy in him? one dr suggested cow milk can be given so I gave him once, is that the culprit or some other allergy has triggered him. pls let some doctor help me out to know better about this condition. my husband's mother have wheezing does this mean my son wheezing is genetic?
