Have a pain in neck and base of neck and arms and legs feels slightly prickley and slight lightheadedness...any ideas? Thank you

I suspect stress/anx. Stress /anxiety can affect our bodies in many different ways. Most often they cause vague muscular aches and pains particualrly in head and neck muscles. I would ask you to look deeply into your daily life and find some time for relaxation. Exercise is one such effective option. Even a short walk gets your mind off from the stress of your work. Find time for a short walk any opportunity you get.
