Thanks to Klaus whom pointed to some links on TBI and vision problems - I found Visual Midline Shift syndrome which could explain my blurred vision, tracking problems, balance and a rather strange forward lean.

When I asked a retired Neuro guy about this, I was told to stop trying to find out what was wrong with me and leave it to the professionals. I explained that I haven't been examined yet and not likely to be for another 6 months - who else was going to get me better - he was not swayed
