Update.

Sorry but I take it all back. There is without a doubt a bone irregularity/discontinuity in both my tibia and fibula that is incredibly, immediately and unwaveringly obvious. It feels like a previous fracture though I am not qualified to say. I have had two registered nurses (one also a practising midwife) confirm this observation with absolute confidence. It can be felt through the skin and I am no longer open to any other suggestion besides a bone problem. I suspect that this also explains my bone impingement upon dorsiflexion since the joint is out of shape.

Question: why can I only sometimes feel this? It seems as if there is a tissue/fluid build up and if I spend the effort pushing it all away I can finally find it and then others can come along and easily confirm it. An hour later it is all gone and it is then difficult to locate (making me look silly when I say it is obvious). Does fluid build up in these areas or something? I really need a doctor's confirmation so that I can put an end to this perpetual hell. I'm afraid that my next doctor visit will be another unsuccessful attempt to locate this obvious problem that has gone undetected by 3 Wikipedia reference-linkMRIs.

Sorry about the emotionalism. Why am I apologising to a text box? Send
