Hello. I was wondering if you could answer some questions for me. Firstly since 2013 I have been having these issues with headaches that occur. They're quick jabbing ones that go away in about 15 seconds. I had an Mri in 2016 and it came back normal. Recently in the last two weeks though I have had bouts with my head feeling like there is a vise wrapped around it. My doctor has done all kind's of blood work including a C-Reactive Protien and a SEDIMENTATION RATE,AUTOMATED and they both came back normal. Actually everyone of them has come back normal. I have had times where I get a little dizzy and it comes and goes. The brief headaches I get are not screaming at any means. Also I have this feeling that something is pulling in the middle of my head and also in the back. My tempals sometimes feel like they're throbbing as well I am working on seeing a Specialist to see what is going on. My doctor doesn't seemed to worry as he thinks it could have something to do with my allgeries and sinuses. Does this sound like it something I need to worry my self?
