Well I saw the neurologist today. She thinks the concussion is causing my migraines and she ordered an MRI of my neck apparently my other MRI was for my brain I guess , and she ordered an EEG. She put me on some meds for my dizzy spells and to kill the migraines when I have them in addition to the topomax that my primary care doctor put me on to combat the migraines. Roadrunner to answer your question yes someone else's insurance will be paying for this as another party was at fault since I was rear ended. I just want to get back to work . I ask the neurologist how soon it may be and she said we would talk about it in a couple of weeks after the MRI of my neck and the EEG.
