so these tumors are on the outside of the brain? on the bone or in the tissue between the bone and skin?

nothing is showing inside the brain area correct?

sorry just trying to clarify for myself.

[The pain is getting progressively worse and is keeping me up at night. I am also having abdominal pain and am noticing the vision in my right eye is being affected somewhat.]

did they only MRI the head? or head and c spine?
maybe a more comprehensive MRI or CT? more area checked?

If no other spine, bone , tumor problems show on the testing -
possibly trying an expert chiropractor for the headaches - esp if you had any previous hard falls, sports injuries, head or shoulder hits , car wrecks etc??
if you decide to try that interview and check them out well
look for uppercervical treatment by DC also.
just a suggestion
