A common cold is frequently accompanied by a cough, body pains, exhaustion, and sometimes yellow nasal discharge, in addition to a runny nose. Each of these symptoms should go away in just a few weeks.
Allergies develop shortly after coming into touch with certain allergens that cause them. They are accompanied by clear flow from the nasal, runny nose, and eye irritation and the symptoms last as long as the allergens are in touch with the body.
