HI Melina,

Sorry to hear of all you pain. I am not sure if it will help you... I also have bilateral TN and ON. I do get the pins and needles feeling all over the back of my head, and forehead.. along with all the more painful things with my ON. Though I do have TN in all 3 major branches. But for me I can tell them apart, as my TN is classic, in that it is electric bolt type pains, and the ON isn't. Hope that helped a little. Best of luck on your new med!!! Nikki
