Has anyone ever experienced this? Whenever I get up from sleeping or even a nap, when I yawn, my entire body trembles uncontrollably. Any idea what causes this?
Hi herodog,
I noticed no one answered your question. I experience whole body tremors when I yawn and stretch at the same time. Is this what you are talking about?
No worries,
It's just that with bfs, when your muscles get stretched after not using them for a while, they might go into little tremors for a few seconds. This happens for some folks when they work-out or overwork a muscle as well. Even people without bfs get shaky sometimes. It is all normal.
