Sir, I am a 20 years old boy, my jaw is restricted to 2 fingers opening only since my childhood, not 3 fingers opening like others. Though I never experienced pain in my life and I am able to food, but still, I am not able to swallow foods like golgappe etc. My teeth are not properly aligned, I have cross biting in my teeth. When I don't eat food for hours I often feel clumsiness in my mouth area. Sir/Madam, is it related to any neuro problem or is it tmj or trismus?
