Facial asymmetry exactly like bell palsy only never been paralyzed. I had it for about 15 years. After meals I feel like one side of my face is stretching and there is pressure around the eye, I also suffer from vaso-dilation symptoms like heat urticaria and flushing also after meals, hot showers etc. 28 male BMI 16.
Your symptoms are not fitting with commonly known neurologic diseases. Bell's is normally not fluctuating after meals.
I used to get flushing and crazy sweats after big meals when I was college, especially around certain people. It went away after my life became more balanced. I never felt it represented a disease, just an over active sympathetic nervous system because of life stressors I lost control of.
