Just an update.

I saw an orthopaedic surgeon today who has ordered an Wikipedia reference-linkMRI of the very specific areas of intense pain along my fibula (there are two very specific spots - about 25mm apart). I will do this on Tuesday 13 January. I have had friends and family confirm that there is certainly an abnormality along the bone as if someone has broken a rod in half then glued it but the surfaces didn't mate correctly. This can be felt at the two spots along my fibula (about 80mm and 105mm above the tip of lateral malleolus).

While I am on the verge of a diagnosis (529 days after the injury!), the condition is now so bad that I cannot walk without a brace (orthodic boot) and even then it is painful. This means I only do essential weight-bearing such as going to see a doctor. i.e. I am in jail for good now.

Thanks for the advice from this forum so far.
