Is sneezing often just a cold?

Not necessarily. A cold often comes with a sore throat and a mild fever, and it usually gets better on its own in about 1 week. If sneezing happens often, the nasal discharge is clear and watery, and the nose itches, and the symptoms last more than 2 weeks or come back at the same time each year, allergic rhinitis is more likely. It is a good idea to go to a regular hospital's allergy department for an evaluation.
