sever localised headaches .... and i feel kind drunk !

Guys and Gals

Been a heavy smoker, for about 5 years, the last 6 months have seen me using more green, as i am chasing the same stone.

Recently, i have been getting these severely localised headaches, and i mean agonizing, sometimes it feels like there is so much pain concentrated on the one spot in my head, and my vison can go a bit wierd to, like a migraine, and i have found the next day, when i am not stoned, i feel kinda woozy and dizzy, kinda light headed, and not quite all there, i move my eyes, and my head follows a second later, basically like i have a really bad headcold. o.O sometimes i get a thing, where the back of my neck and head feels quite wierd, kinda tight and numb

Its been especially bad today, and last night i had pain in my head so severe, the i couldnt open my eyes, i had a loud buzzing in my head, and i thought i was gonna pass out.

Is this withdrawl symptoms? needless to say, that nothing last forever, and as much as i could use a cone after work just to go "aahhhhhhhh" and unwind, i cant, as i am scared i could have had a mini stroke or something.

anyone else experienced this?

thanks
