The differences between allergic rhinitis and the common cold are very clear. Allergic rhinitis lasts longer and causes patients to experience sudden bouts of sneezing in the morning, continuous clear nasal discharge, bilateral nasal congestion, and also includes symptoms such as itchy eyes and nasal issues. On the other hand, the common cold generally lasts for a shorter period and is usually caused by a virus or bacteria due to lowered immunity, leading to both systemic and local symptoms. Patients with a cold may experience fever, dizziness, headache, muscle weakness, muscle soreness, nasal congestion, sneezing, runny nose, sore throat, and coughing. In terms of treatment, allergic rhinitis requires symptomatic anti-allergy treatment, while the common cold needs symptomatic anti-inflammatory treatment and generally improves gradually over about a week, whereas allergic rhinitis requires a longer process.
