Neck/Headache for two weeks?

 I’ve posted before, but this worry is seriously ruining my life and I don’t know where else to turn. About two weeks ago I got hit with a pretty bad cold and headache from the left side of my neck to my ear. I started getting dizzy, my ear felt full, and starting getting muscle twitches. I went to the ER twice. The second time I went I got a CT scan with Contrast and they said everything looked perfectly normal. They weren’t able to see “part of my cerebellum” and when I heard that I flipped out. I went to my GP and he did nothing. I went to urgent care and the doctor did a nurulogical exam and said I was fine. She refused to send me for an MRI because she thinks I have anxiety. I know I have anxiety but these headaches still won’t go away, I’ll get these weird sharp pains in my head that freak me out, and I can barely sleep and eat. My eyes hurt. And I’m constantly thinking about it. Should I insist on an MRI?

Are the headaches and neck pain your only symptoms Now ?

I have pain in my left shoulder and hand. Light headedness and a very tight stomach. 

Could be tension headaches. You should get your heart checked out or see if your having circulation problems.
