I Have Epilepsy And Recently Have Been Suffering Mind Throbbing

I have Epilepsy and recently have been suffering mind throbbing migraines, to the point of having to leave work. I was wondering if Migraines and Epilepsy are tied together in anyway. I have also noticed what feels like a pressure inside my head that feels like a pulsing in the brain with tunnel vision and then this turns into a headache if not pressure there is a feeling of weight on my head. I seem to be suffering from daily headaches, most of these headaches come with extreme neck pain.
Is there a chance that changes are going on that I should be concerned about?
