Can a flexible laryngoscopy damage any of the pharyngeal muscles involved in swallowing? how well protected are these muscles and how strong are they? i felt pressure and pain in throat during my laryngoscopy is this bad and what could it have meant?

Laryngoscopy: It is possible to irritate the the posterior pharynx and larynx wit a laryngoscopy. However, this should be something that would resolve in a few days. If the procedure was done emergently that can be associated with more complications or for example if a person were on a blood thinner and needed immediate procedure. As a rule the procedure is pretty safe.
