there are a few possibilities. first there actually could be something caught in your throat but this would take a thorough examination by an ent (using a fiberoptic scope) to make that call. second: inflammation from variety of events including reflux (perhaps from a hiatal hernia as you mentioned) something compressing your esophagus (thyroid? ) irritation from food/medicines/smoking etc. third: it could be psychological but before anyone tries to make this assumptiion all organic causes need to be ruled out.
