Well, it's time for you to describe in more detail what you were doing
so first , breath in and hold your breath .
then either use your one hand to act as a clamp and press your arteries or use your thumbs to press the arteries separately . remember to hold your breath all this while . Also blockin jugular vein and the carotid artery got different results .
for jugular vein - you would feel like your head is filling up or getting hot on the back side while for carotid you will experience dizzyness .
also sometimes both of these might occur simultaneously , as here you press both the vein and the artery .
everyone once try it out and check how you feel .
