The problem is that the bone between my sinus and eye has eroded. A load of blood tests and CT scan since Friday and an op. in the very near future.
Thank goodness I had sorted out my B12 problems before this, thanks to the private doctor I went to when my NHS ones refused to give me any more inj. after the 5 loading ones. (see previous posts) I could not have coped if it was still deficient.
I know that nitrous oxide (for anaesthetics) wrecks B12 but does anyone know a reference for this. I would like to take a copy to the hospital with me. Thanks.
