Sinusitis: Sinus infections are a common cause for excessive post-nasal drip. This diagnosis is commonly missed by physicians who mistakenly believe that clear nasal discharge is definitive proof of the absence of infection. A cat scan of the sinuses might be needed to detect a low grade chronic infection.
