Intercranial Hypertension is normally not caused by anxiety disorders. I have intercranial hypertension and it is believed to be caused by a genetic clotting disorder that I have. Somethings that can affect the pressure is stormy weather. When we have storms ( I live in Ga. USA), I get one monster of a headache. With these I also get knotted muscles at the base of my neck and shoulders. The noise is also in my right ear and can drive me crazy. There is no way to turn it off.

Do a search for th Intercranial Hypertension Research Foundation. They have a wonderful website that has all types of information on IH, also called Pseudo Tumor Cerebri. Hope this helps.
