Well not quite!  I went for an MRI on my knee to rule out cartilage damage.  As suspected, everything is hunky dory and the MRI showed only inflammation in the side of the knee, which was explained as ITB Tendonitis.  There is no easy answer for treating ITB Tendonitis and different methods work for different people.  I was offered a Cortizone injection but after a little reseach, decided that was not a route I wanted to go down. 

I can continue with my running (I am not causing any damage), the Physician informed me that people do manage to run marathons with it and some have no problems.  I am treating it accordingly - ice after training, anti-inflammatory cream on the affected area and regular Ibprofen to help keep the inflammation under control.  So far, this seems to be working successfully. I will be sensible and am monitoring it closely.

 
The situation now: I am no longer getting pain in side of my right knee when I run and I believe that my run/walk strategy for my endurance runs is really paying dividends. However, I am experiencing a discomfort at the bottom of both knee caps which I am treating.  My left leg has been showing similar symptoms to the right, I believe this was caused by the incorrect shoes I was given on my second Gait Analysis five weeks ago.  I have since been for a third analysis and had my shoes corrected.
 
I am now breaking-in the shoes I will be running TWO marathons in!!!
