Like many of the posts on your homepage, I am experiencing shivers in my head and sometimes down the right side of my face ... probably one or the other every other day or so. As well, I have been experiencing blurry vision since last spring that has increased and is present almost every day at some point. I have had a thorough eye examination and the doctor has concluded that this is not an eye problem, but a medical one. I have a lot of headaches, generallyf on the right side. I am waiting for an MRI to investigate further. I feel that there may be a tumour on the left side as there are several spots that are tender to touch. Any thoughts?
