Is there a reason why i lose/cut circulation in arms and legs really very fast? have to change positions quickly bc can feel numbness coming on

Circulation: Numbness is not necessarily the result of poor circulation. It's unusual to have circulation problems involving both arms and legs unless you have some sort of systemic vascular disease such as vasculitis which is quite rare. Numbness can occur after assuming body posture that may temporarily compress the nerves/arteries but that quickly goes back to normal after you move.
