Constant headache. A neurologist for it.

I am having headache for past so many days now. I take saridon, and it goes away and comes back again in 3 hours. The pain is deadly. Sometimes it reaches till my teeth and gums. It starts from the centre of skull, on the top left side, and reaches all over my head. Sometimes I feel pukesh. Apart from this I am having difficulty in going in car. If I look only for a second to my phone screen, I feel pukesh. Also feeling sensation on palms of my hands and feet while sleeping. It's so much, that I have to put water to it to feel better. Also I am consulting psychiatrist for OCD treatment, but my above problem has nothing to do with my psyche, as my psychiatrist only recommended me to consult a neurologist for it.
