Vascular headache. Go see a neurologist?

I'm a 19 yo girl. I have headache since a long time. Visited many doctors nothing helped. I feel very giddy and nauseous all the time. Head hurts like crazy even by slightest of noise. Have become light sensitive also. Im confused a lot and fumble while talking. I wasn't like this before. The pain is usually throbbing whole head hurts but mostly the left side and forehead. Headache usually starts after sunset. Or early morning. I feel giddy and sick even if I lie down. Very restless. Recently a doctor told me that i have vascular headache maybe and he suggested i go see a neurologist. I looked up the term on the net. Looks serious. Do i have to worry? Should i go see a neurologist? I'm tensed. We had gotten some tests done and also an MRI of nose which showed nasal septum deviation. Didn't get the surgery done but it's completely gone now. No sinus. No sneezing. Nothing. But headache has worsened. I cry out of pain many times. It has disrupted my life totally donno what to do. pls help
