Hello,
As other people already suggested you to visit a Neurologist, I think you should visit a neurologist immediately . Although I am not a medical professional, but I know that MRI scans are better than CT scans. I think, if you just do a MRI, it will not be that helpful. Normally a neurologist tells the Radiologist what to look for. So Radiologist puts extra attention on that area.

You also mention about "Body Vibrates", did you mean about Seizure? If that's the case definitely you should see a neurologist. I do not want to make you scared, but headache can be sign of so many things -- Hydrocephalus, Brain tumor, etc. From my experience, I have found out that brain is the most complicated thing in a human body.

Good luck.
