I've noticed for the last couple of years I get what seems very frequent headaches, at least 2 a week. Recently in the last year or so I have been experiencing severe, sudden & sharp pains in my head. They come & go, it's not a consistent pain. For example, last night I went to rent a movie & out of nowhere on the right side of my head, above the tip of my ear I felt this sharp, stabbing pain. For the next hour the sudden pain would come & go, & it would hurt extremely bad each time. Of course my immediate reaction, or reflex was to grab at that side of my head, my boyfriend asked if I was okay each time. Late last year I saw a local neuorologist who wanted to do either a ct scan or an mri on me, I wanted to except that I don't have great insurance and it was going to be $600.00 out of my own pocket after insurance covered what they would. I'm wondering if there is any cause for concern to have the testing done. I know there are so many headaches out there like tension, cluster, rebound & sinus, so I don't want to confuse one of these as a possibility to what I may have and waste $600.00. I'm also not sure if the frequent headaches tie into the sharp pains. Please reply soon.
