Hello, for a week now I have been dealing with severe head aches, dizziness, and feeling lightheaded. I almost passed out a work a few days ago. Now, for a few weeks I have been under serious stress, stopped eating and sleeping. I am aware this could be part of the reason that I am feeling this way. However, I have been resting the last few days, just sleeping, drinking lots of water, even eating, and taking vitamins. I have not improved at all. I was wondering what could be the problem and if I should go in to get it checked?
