I haven't been diagnosed with anything yet but I seem to have all the symptoms of ON. My doctor, Neuroligist and Neurosurgeon all tell me there's nothing wrong with me to cause those type symptoms...pain in neck at base of skull, dizziness, eye pain. Do you notice that if you lay in bed, on your back, head on a pillow, that the pressure increases and you have an intense ringing in your ears that sporadically peaks the dizziness?
