Hello, I am wondering if anyone else has had symptoms like this, and what it could be! I have had migraines for years now, and I am currently really concered with the headache I am now having. The head pain is in the back of the head on those knots towards the bottom of the head. I have had memory problems, vision problems(blurred, and double), numbness in just my right hand, and both feet, tighting of my chest(which comes a goes), very dizzy, last night really scared me though. I woke up and my heart was raceing and would not slow down for an hour, and then just stopped, and all day today so far I have been very weak, very tired, and my head hurts in the back...My mother had 3 anneryisms of the brain, and about 6 years ago when they said my headaches were migraine, they checked for anneryisms and say nothing, what could this possibly be....I do have a thyroid inbalance, and have been told I'm hypoglycemic. I just want to feel better and have this headache go away, it has been a few weeks of dealing with this, and no relief really and I just keep getting more symptoms....Thanks for any help!!!!!
