PFFD VSG2

I am 54 and found out 2 weeks ago that what I have had all my life is actually called PFFD. I was hospitalised at 15months old for 7 years at Chailey Heritage in Sussex. I had a bone graft at 3years old ( which I understood later had not worked). I was allowed to get a contraption strapped to me that let me walk at the age of 7 or so.
Once freed from a bed I was very active. I went through various types of supports. My PFFD, (I am not up to speed on all the terminology yet) is on my right leg with a femur length of maybe 2'' , its a guess because I have never been shown an x-ray. I had a Symes amputation when I was 16. The foot was perfectly formed and was actually quite an aid to walking as it gave a more positive feel to the direction my artificial foot was pointing in.
I played a lot of sport (that didn't need running over long distance) and could hold my own in a fierce game of volleyball.

I am father to 10 children of our own and they take no account of my disability, which is great.
I am about to have some x-rays taken of my hips and spine as I am beginning to experience pains that I cannot account for. I have been informed by the limb centre doctor that this is common for amputees. The information would have been helpful earlier in my life, it has all come at once, after damage to my body has been done.
I have never let my leg dictate what I can or cannot do, this has helped me achieve all that I have in my life so far.
I am self employed as a property maintenance contractor. I have basically self diagnosed my self and any pains that happened myself because I was left with the impression that there was not a lot to be said or done about it, just get on and see what happens.
