Hi, I am 21 years old and I have been getting this really uncomfortable crunching in the back of my head when I turn my head side to side, then there is usually some pain to follow. I also get a weird grind like feeling when I tilt my head to look up and it hurts after that aswell, (sometimes as it happends). then I feel a little dizzy and off balanced. I also get some pressure in my head that follows these symptoms, and I was wondering what that may be. It is really worrying me and some medical advice or opinions would be greatly appreciated. Thank you.
