For The Past Two Weeks I Have Had A Fuzzy

For the past two weeks I have had a fuzzy feeling between my eyebrows and mid forehead. I have recently returned from long flight of 16 hrs 3 weeks ago. I have tried sinus medication in case it was some trapped fluid however they seem to make me feel worse and a bit spaced out. The sensation comes and goes up to 4/5 times each day and lasts about 30 minutes or so. I'm wondering if it is because I have low blood pressure 90/60 or could it be my eyesight (I wear multifocal glasses and find it diffucult to focus on different areas at times) or possibly a pinched nerve in my neck? I have had blood tests done and checked B12 and Iron etc which are all good.
