I buzz, or I call it vibrate. It is in all my limbs, but my hands are the worst. When L'Hermittes is acting up, I dip my chin and zap my hands. Ahh, it hurts to think about.
When getting an MRI, it gets worse and the anxiety it creates is intense. Pushing a shopping cart in store or parking lot is nerve frazzling.
You are not alone. I just wish there were something to take it down a notch or ten.
