These are symptoms that I get which are from my TMJ problems. The muscles in the shoulders, neck, and head/jaw create pressure in my ears, numbness on one side of my face, and squeezing of my head (sometimes it does feel like that band). When I am overloaded by stuff that i am hypersensitive to it is worse, and when I try to detox it worsens. I'm sure it is caused by the mercury, but physiologically it is related to the TMD. If you look up symptoms of TMJ/TMD you will see these things described.
