I Have Had A Year Of Head Trauma, Including Multiple

I have had a year of head trauma, including multiple biopsies 2 MOHs surgeries and chemotherapy. I started having some pretty severe sudden onset of pain on the right side top of my head. Sometimes it hurts just to touch that area but the pain doesn't last very long and some days I can have up to 6 or more pain and other days none at all. My dermatologists and my m d both think it could be a nerve. I have had a mri with and without contrast and didn't show anything. I do have an appointment with a neurologist next month.
