Cold vs Allergies?: It appears that you may be suffering from allergies: hay fever (allergic rhinitis)-> irritated throat from the post-nasal drips if these symptoms had been present in the past or present for more than 3 wks. The coughing may be from the post-nasal drips and/or asthma. On the other hand, if this has been present for just a week, it may just be a cold.
