Yes... I Am Having A Funny Sensation In My Head.

Yes... I am having a funny sensation in my head. I have it a lot. My doctor has told me I am dehydrated and need more water. I weigh 110 lbs and drink 150 oz of water almost everyday. Never less than 100 oz. my blood pressure is always around 105/68. My head feels like it is kinda pulsing with a heavy feeling. I have a lot of headaches across my forehead.
