GF,
You wrote:
Should I be off work?
Should you fly?
It sounds as though your balance organ is off sync. (But not able to diagnose/treat on this forum of course)
Some of the symptoms you describe are in keeping with that (labyrinthitis) but some fit in better with a concussion (despite the absence of loss of conciousness, vomting etc)
In view of the persisting symptoms a re-visit to your GP seems a good idea and until this is sorted I would leave my flying gloves at home.
