Stuttering - Eyeball secondary behavior.

Stuttering - Eyeball secondary behavior. Hello guys. I'm a stutterer. I work as a policeman, so I frequently need to use my voice. I've been trying my best to avoid every secondary behavior I learned throughout my life (such as taking gulps of air, blinking rapidly, looking away quick). However, I've noticed, sometimes while I'm blocking my eyeballs they feel like... they're burning a bit? Does anyone else have this sensation? Is it because I'm trying to avoid secondary behaviors, so I consciously refuse to blink and it causes this feeling? Or is it a secondary behavior? Let me know if anyone else experiences this... thanks!
