Migraines since involved din explosion.

[Troop123]

I was involved in an explosion in 2011. I have been suffering from migraines and tinnitus ever since. When I have an episode of migraine, the right side of my head hurts more (including the right eye). Most recent, I am experiencing short term memory loss and I have pressure build up in my right ear (unable to pop my ear); I am experiencing pain behind the ear. I was seen by ENT and I was told that there was a slight mucus build up but nothing severe enough for a Eustachian Tube. I was also see by an audiologist, I have mild hearing loss to high frequency noise in my right ear. Can someone please explain what the findings may be?  

This is the results from my MRI:
FINDINGS:

Brain is normal in morphology.  Normal gray-white differentiation is maintained throughout.  There are confluent increased FLAIR signal hyperintensities within the white matter tracts of the occipital poles bilaterally without expansion or other similar signs of mass effect.  This could represent remote posttraumatic ptosis, artifact, or in the right clinical setting an acute hypertensive encephalopathy (PRES).  There is also a singular more focal T2/FLAIR signal hyperintensity noted in the subcortical periatrial white matter tracts on the left.  While this could also represent posttraumatic gliosis, it may represent a small development venous anomaly based on configuration are.  There are no signal abnormalities to suggest ischemia, mass, or hemorrhage.  This includes microhemorrhages (none are seen).  CSF spaces are normal in size, shape, and symmetry; there is no mass effect.  Posterior fossa structures are normal.

Orbits are normal in appearance.  Sella is normal for age and gender.  Soft tissues of the face and skull base are normal.  There is mild mucosal thickening and an air-fluid level noted in the right maxillary sinus, along with a few opacified anterior right ethmoid air cells.  Frontal sinuses appear aplastic.

IMPRESSION:

White matter signal hyperintensities in occipital lobes, and a similar focus in the white matter tract, potentially may represent posttraumatic diagnosis, can't exclude PRES or artifact, see remarks.
