yesterday, i felt dizzy and very cold all of a sudden at work.  I had jelly legs and headache.  I felt like I would throw up or faint.  I went home and slept for hours and hours, and I sweated a lot...  I still have headache and feel weak today, but pain in my legs are gone.  What is going on with my body?
Hi, You have not mentioned your age, so it is difficult to diagnose. But commonly these symptoms are seen in low blood pressure conditions. So meet a cardiologist and find out whether it is secondary to some cardiac problem.
