For those of you who replied to my last post 'still not up and running' just a quick update.
I've been back to the hospital (twice in the last 14 days both times I was there for 4+ hours!!)
After yet more xrays, blood tests, MRI scan, ECG and lots of prodding and poking they have decided to remove all the metalwork. I almost certainly have an infection that has attached itself to the plate they put in. The positives are that they have found no evidence of infection within the bones or any osteopenia (a lesser degree of osteoporosis) that they were worried about and my circulation within my leg/ankle/foot seems ok.
So sadly I'm still unable to do much more than walk (with a limp) and I have joined the waiting list for day surgery.
