The entirety of today I have had a headache that feels like “static” it’s not a throbbing pain like a regular headache but a peircing uncomfortable feeling all over my head at random parts, as well as on my face , arms, legs etc . 

I can feel it in my nose as well. In addition to it I feel just off and dizzy. 

I’m trying to sleep right now but it’s keeping me awake as it feels like low blood sugar , and I keep jolting awake but I’m absolutely exhausted. does anyone know what this could be ?? It’s scaring me 

I’m tapering off of Xanax but I’ve been on the same dose for a couple weeks now taking a break before tapering again so I’m not sure if it’s related or what .
