Thank you very much for responding.
Today the headaches are still here, and once again they seem to be isolated mainly on the left and right side of my head. My vision is fine today, and the pressure has let up somewhat as well. I was thinking about making an appointment with my doctor and at least mention my peripheral vision concern. It just freaks me out because this has been going on for some time now, and I feel like it will get worse. I have been pressing on the top of my head and instantly that brings me complete relief - that worries me too.
I have not been dizzy, had loss of balance, etc. But, I have had a painful neck (mainly my spinal area it seems like). Occasionally I will have pain behind my eye as well. Has anyone else had this happen?
