Sneezing and cough ?

Possible allergies: Sneezing is a common symptom of allergies. While cough can be a symptom from multiple causes, it also can be related to post nasal drip from allergies. Also, cough is a very common symptom of asthma; frequently asthma and allergies occur together especially in children. If either cough or sneezing interferes with sleep, daily activities, exercise or becomes persistent, it is wise to seek care.
