Your mouth breathing may be causing the dryness in the throat, which in turn will cause the sensation of swelling.
It may be chronic sinusitis, with an excessive postnasal drip, or perhaps a deviated septum, which causes problems with nasal breathing. You should see an ENT for a full examination of the upper airway, this may include a nasal endoscopy, or even a laryngoscopy, which is the examination of the nose, and/or throat with a small endoscope.
