My name is Dave and I am having similar symptoms. I have been dizzy, stomach upset and visual disturbances with migraines following. I hadn’t had many migraines lately then two over the last week. I also have a “buzzing or pulsating when I lie down and can’t for the life of me figure out where on my body it is originating from. I wonder if it is related to a response with allergies? My kids have had colds. I have also had weakness in my legs and pain in my neck. I have been very frustrated with my doctors and feel my care has been fragmented. I chose a medical plan that didn’t cover out of network so I have to jump through a bunch of hoops to try to get to Mayo. I am hoping the neuro doc in Ia City will send me on but he is dragging his feet. Just looking for some answers!
