I have the same issue!
My eyes have been the problem- especially one side. Occasional slight pain above the eye, but mostly goopy, blurry etc, for which no Dr. could see a reason inside the eye.
Trigeminal Neuralgia was listed the MRI interpretation by the Dr. administrating the test: MRI BRAIN WITH AND WITHOUT GADOLINIUM. He stated everything looked normal except some subtle evidence of enhancement through the descending facial nerve on the left, this can be a variation of normal but can be signs of inflammation as well.
The neurologist said "it's nothing", did nothing, recommended nothing and I remain the same with problems in my eye and a debt on my credit card.
