I have suffered anxiety for years. about 5 yrs ago I started getting pressure behind one eye, with heavy pressure across the bridge of my nose, a pain in one side of my head with alot of pressure. I get nasal drip too. I was convinced I had a tumour, so I had a MRI scan and all clear !! I have been getting it on an off for 5 yrs now, sometimes daily, It can only be anxiety for me, or maybe the anxidety messes with my hormones and causes sinus isssues , I dont know.
