Hello. Thank you for asking at Chat Doctor. I went through your history and would like to make following suggestions for your son:1. If he as both asthma & skin allergy, I would suggest him allergy testing for air-borne and food allergens. This will help you identify the substances that he may be allergic to and also to know the measures to avoid them.2. Common air-borne allergens causing allergies are - house dust mites, molds, pollen and animal dancers. Common foods causing allergies are - milk, peanut, wheat, soy, eggs, tree nuts, fish, seafoods, etc. He should avoid only those foods to which he is allergic to.3. The medicine that he needs would depend upon severity and frequency of his diseases. So more details would require to advice about medications. In general, I would suggest him to use albuterol inhaler for wheezing/breathing difficulty symptoms and he as asthma symptoms very frequently, I would suggest him daily montelukast. For skin allergy, I would suggest him regular application of lotion like calamine immediately after bath to retain moisture in skin. If he still has symptoms, he might require corticosteroid creams.4. Climate is important for air-borne allergens like house dust mites, molds and pollen. So, yes, it does have effect. Especially humidity increases both house dust mites and mold concentration. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish your son the best of the health. Thank you & Regards.
