I keep getting like a pins and needle feeling in my head. head ct all normal and clear 2 weeks ago. what else could it be am i dying?

Nope. Not dying.: Anxiety!!!! As a response to anxiety or stress and activation of the fight or flight response, you get a change in blood flow to the brain which can cause that tingling sensation. Treatment involves decreasing your stress & practicing relaxed breathing & relaxation techniques. Sure, the tingling in head can be unsettling and even bothersome but since the scan was negative, you should be reassured
