Allergy is when the body has become sensitized usually to something external, explains Dr. Javier Hiriart, Pediatrician at Family Medicine Center at West Kendall Baptist Hospital.

Allergic rhinitis or the manifestations of allergies in the nose (the upper airway can), the Doctor explains, manifests from as sniffles, as itchy or sore throat post nasal drip or has some of the effects of sinusitis such as getting fluid trapped in those sinuses and, sometimes, conjunctivitis.

Having family history and asthma are linked, since people that tend to have allergies can also have asthma because they have common pathways that they can manifest, although not everybody will manifest all of those symptoms.
