Quivering feeling around bladder?

[SoftFuzzy]

I don't think my bladder's quivering, because my urination's normal, but it's in the same area. Ever since I got to college some muscles above my groin but below my pantsline quiver a lot when I lie down. It's not painful but it's distracting.

Could it be because of my diet? I'm eating a lot more carbs here than I used to. Does anyone know why this could be happening?
