i am getting tired of this pain in my head, i had an mri and an mra, both came back negative yet i still worry. what do i do? its likes the icepick, but somtimes its not it will last alot longer than it used to...neuro tell me it's just anxiety and stress and to just exercise, and try to relax but how can i relax when im always in pain..one says it may be related to my neck, the other says it's a blood vessel, what is going on in there? should i have another mri and mra or should i just trust what they are telling me? :(
