Cold: A cold is a viral infection that affects the upper respiratory tract, causing symptoms like a runny or stuffy nose, coughing, and sore throat.
Allergies: Allergies, on the other hand, are caused by the body’s immune response to allergens such as pollen, dust, or pet dander, resulting in symptoms like sneezing, nasal congestion, and itchy eyes.
Sinusitis: Sinusitis is an inflammation or swelling of the tissue lining the sinuses, often caused by a bacterial infection, virus, or allergies, and can lead to symptoms such as facial pain, nasal congestion, and thick nasal discharge.
