If you feel your feet and hands are tinging and you feel a bit out if it some days?

Tingling: Most common cause of tingling of both hands and feet at the same time is anxiety, through a process called hyperventilation. With anxiety, your Adrenalin is higher than normal, making your heart rate and your breathing go faster, with the faster breathing (which may be only repeated deep sighing), your carbon dioxide goes low and causes the tingling. The anxiety would also make you feel out of it.
