Thanks to all that offered advice. In the past week I was admitted to hospital as the headaches became so severe and my eyes became worse. I was given a lumbar puncture (not so pleasant) and a mri, these came back as showing nothing, but at least ruled out anything organic. I now await my appointment with a neurologist and off we go again. Frustrating. Boring. Fed up. Anxious!!!! I am aware that it's possible to put my eye and head issues down to being related to CRPS but I will push for other tests as it could also be something completely different. Excuse poor grammer, eyes sore so I'm coming off the computer bye for now.
