Diagnosing allergies involves delving into a patient’s medical history coupled with diagnostic tests. If an individual experiences two or more symptoms—like a runny nose, sneezing, nasal congestion, or itchy nostrils—persistently for an hour or more on most days, allergies are likely at play. For those battling specific allergies, immunotherapy stands out as a promising treatment option. This comes in two forms: sublingual immunotherapy (SLIT) and allergy shots.
