Just thought I'd post to say that my MRI of brain came back ok. So another example of how anxiety can group all the symptoms I was having, make them worse, and end up with me thinking they were all related and therefore something deadly. For anyone else having same sort of fears I thought I'd outline my symptoms to highlight how no matter how bad they sound all listed together, can still result in nothing major wrong.
Off balance
Severe headaches across forehead and base of head
Middle of night insomnia
Stabbing eye pain
Issues with vision/focusing
All getting worse over a 4 week period
So turns out all 4 areas of my sinuses are fairly blocked up which they said would account for most of my issues. I also saw physio today and a knot in my neck/shoulder area when pushed on re-creates the pain I'm getting in my forehead, which accounts for that. The rest of course was amplified by anxiety!
