Me!! I have been having headaches almost daily since last August. I went to my neuro, who is awesome, and told me is due my shoulder and neck pain. He gave me trigger point injections and that helped a lot. But I still have the headaches.... I told him I need to rule out a brain tumor, that was so scared that was causing my headaches and he went and get me a prescription for a MRI and he said "I am doing this for you, not for me, because I know you don't have a brain tumor"
Another thought, I have low ferritin (low iron in my blood) and that can cause headaches. I am taking an iron pill every day.
Headaches are annoying I know!
