Historically she has suffered from a 'trapped nerve' pain and this has got worse recently. After an unrelated trip to see her favourite consultant at the hospital, and me describing all the events surrounding this added pain, the consultant decided that he was going to x-ray.
It turns out that she had broken her femur, hence the pain, and has been walking on this leg for so long that the crack has started to heal. As one doctor said to her 'we have no idea how you did that, they don't make them like you any more.'
She has been offered to have the break reset and pinned but she has refused because she can't stand the thought of having an operation at her age and doesn't want to spend any more time in hospital. She is about to discharge herself.
If we went to war I'd want her on my side!
