I have had a lump on my throat for the past 9 months. Its swells up causing left side body numbness with right side of head numbness. It feels like someone is choking me. I feel confused and faint when this happens. Its like an attack that last for hours and comes and goes when it wants to. Doctors kept telling me I was depressed which was frustrating. I have had an MRI of head and neck in December of 2009. It says it was normal but the findings on there says this "Parenchyma of the brain shows abnormal signal to suggest infarct, hemorrhage, tumor or extracerebral fluid collection." I have a thyroglossal duct cyst which is the size of a pea. About 2 months ago, I have left sided numbness and head numbness that doesn't ever go away unless I'm outside in the heat or taking a hot shower. My neurologist says I'm having seizures. If anyone out there can give me any advice, I would appreciate it.
