For 2 weeks when i make certain movements, eat or move my head to the side my ear pops and others can hear it. saw ent he said i had some inflammation behind my nose during my scope, but that's it.hurts and feels clogged at times. what else can it be?

I assume there was no significant wax accumulation in your ear canal and no polyps present in nasal passages. Inflammation high up behind the nasal passage can clog the eustachian tube and this can cause blocked hearing and various sounds with swallowing, etc. Did ENT recommend decongestant nasal spray or irrigations with ocean nasal spray? See ENT again if pain and/or other symptoms persist.
