hi, first of all consult an ent specialist and get your oropharynx examined for inflammation of your pharyngeal tonsils which is a common cause of recurrent midle ear conestion and ear ache, it can also cause rhinitis and breathing problems. you should also go for xray of paranasal sinuses for detection of chronic sinusitis , polyposis or any other pathology.if you are sensitive to cold and environmental pollution then avoid exposure as much as possible, you can go for complete pannel allergen test and subsequent desensitisation if possible, you should also go for total and differential count of WBC for eosinophilia and its subsequent management.your developing allergy can be managed completely if not ignored otherwise. thanks.
