From Wikipedia: Lhermitte's Sign, sometimes called the barber chair phenomenon, is an electrical sensation that runs down the back and into the limbs. In many patients, it is elicited by bending the head forward.
I started exhibiting this symptom (Lhermitte's Sign) about a month ago, pretty close to the three-month-mark after finishing the Whole Brain Radiation (WBR) treatment. I began noticing it as I worked at my computer because I often bend my head and neck forward to look at the keyboard while practicing typing for the two-fingered. When I look down, I get this tingling sensation running down my spine and arms.
So I told my oncologist and he set me up with an MRI on the cervical spine last week. It showed no tumors or detectible lesions, so I'm hoping this might be a latent side-effect of the WBR. I've read that it sometimes occurs with radiation treatment and when it does, it most likely happens at around three to four months after the treatment is done.
Has anybody else who has done WBR experienced this symptom? Did it ever go away? If so, how long did it take?
