Miracles do happen. My friend Dr Jane the GP called and heroically volunteered to drive me to the hospital in her 4x4. I can't tell you how relieved I was. We made the appointment with a minute to spare and it was straight off to x-ray and then in to see the consultant. Thankfully Jane was there to ask questions which was very handy as I always forget to or don't know what to ask.
The good news is that my leg is still mending. Technically it's still 'non union' but it's getting better. There's still some wobble in the fracture but we're making progress. The bad news is that I still need the cast for a bit longer but I can take it off at night. Even better, the consultant assured me that not only will the leg get better (eventually) but they may even be able to correct my leg length difference. I can't tell you how much that cheered me up. I really am feeling much more hopeful. There's a way to go yet and I know it's a year or so of hard work but I can see a tiny point of light at the end of the tunnel.
Anyway, a big thank you to Jane for stepping so heroically into the breach.
