Intermittent "popping" sensations in upper right scalp, scared of "subarachnoid hemorrhage". could it be muscle tension?anxiety?any advice would help.

GOOD NEWS: It's not a subarachnoid hemorrhage, b/c that's INSIDE your skull. My guess is that YOUR guess is correct, and that it IS, indeed, stress related. ASSUMING your SKIN IS INTACT (if NOT, go see MD) Try closing your eyes, taking slow deep breaths in thru nose, out thru mouth, exhale is longer than inhale, and giving yourself a scalp/face/neck massage. It might be easier to try in shower 1st. be well.
