Symptoms question

After a worst headache 3 months ago where right side face numb and not see out right eye, is it more likely anneurysm if everyday I got symptoms that totally change from right side brain hot flushes, front to rear right sided headache, pressure one spot when you cough, right side neck soreness? Or you feel low serotonin. I went two neurologist and a doctor who prescribes medications. Everyone says low seratonin and I was given zyprexa but never used. I had mri w/contrast and nothing. I want to get MRA soon.

What do you think it is? A shot to left field, I know.
