I have pins and needles all the time but in diffrent area not on my forehead.
I know a.d. is supose to be a numb feeling and it is but I also have a tight tugging pinch... pins and needles when I get one of my head aches it is like there is a needle stabbing into my eyeball on that side. or like a hot firey eletrical poker jabbing at me.and twisting tight tighter it is hard to explain how all the symptoms feel when they mix and match

The area is what I am not sure on AND I hope maybe someone else that has t.n in upper area can help..
I WOULD BRING IT UP TO YOUR DOCTOR and neuro and see what they think and what may be done to help relieve this . really just dont let yourself think it is t.n. make sure ...Ask or at least metion it to neuro /doc and have it put on record so it is in your history when you first noticed this and that you brought it up.
I am sorry I wasnt much help but I got hugs for ya
and keeping you in my thoughts always Melina. low pain and healing vibs to you. hang in and keep us posted.And know your not alone
PEACE
