Hello, smarties.

Any thoughts on what may cause a feeling of a head full of pressure? With ear canal pressure sensation, too?

It's not quite a headache; more like a tightness of the head. I know Cutler says mercury can cause a band-like tightness around the head - but so do a million other things.

I haven't been able to pinpoint a direct cause. It comes and goes, along with some numbness in the left side of the face/head.

Any thoughts on what causes this, perhaps besides mercury?
