I had my gamma knife for acoustic neuroma one year ago this past feb 7... over the last couple of months I've been having more pressure in & behind my ear, more headaches that are close to migraine, face hurting a little....almost like a bad toothache that hurts into my jaw with sensitive back teeth. This is all on same side as tumor, now in Feb my mri read that my tumor was 2mm bigger and where there had been necrosis it is filling back in...my ENT feels that maybe the growth difference is because of my last 2 mri's being different cuts...3mm & 5mm....anyways, I've now been diagnosed with trigeminal neuralgia...gotta say that after reading about it...it scares me almost more than being told I have a brain tumor....My neurologist doesn't know for sure if it is because of the tumor, it makes sense to me that if it is on the same side & just started when I may have growth or swelling of the tumor, that it is because of the tumor. And I'm hoping when the swelling goes down that the neuralgia goes away....any thoughts on this?
