Weird sensation behind head when walking

**when i start to walk, i have this weird electric feeling behind my head. Its like a sensitive feeling behind it. Also i get this weird pressure feeling in the sides of my head only when im walking. as soon i stop walking i dont get it anymore or when im running. I had a ct scan and it came back normal. Does anyone get the same symptoms and what could it be? thanks if you answer i really wanna know if im the only one
