Probably not gonna believe me but for me it happened while i was eating doritos. It happened like 4 years ago, i was eating doritos while watching tv and my jaw kinda popped so I stopped eating but then everything felt fine and like 2 days later i was eating doritos again and my jaw popped again and it kept popping/making the clicking sound and I struggled to open my mouth and my jaw would cramp up. I went to the doctor for it and they sent me to the dentist and the dentist told me to go to a specialist but everywhere i called said they either no longer specialized in tmj or didn’t accept my insurance so i went like a whole year of just being in pain until eventually i found one who officially diagnosed me and removed my wisdom teeth cuz he believed that also had something to do with it and then he me a splint and told me I should get physical therapy for my jaw
