Thanks to those of you that replied when I asked for your experiences.
I had the op just before Christmas and spent 2 weeks with it raised and doing very little walking.
After that I started increasing the amount of walking I was doing. I had to wear an orthopaedic wedge shoe that kept my weight on the heel. I was able to go back into normal shoes after 6 weeks, although because of the swelling I had to go up a couple of sizes!!
The swelling is going down and I can get into some shoes that I couldn't a while back.
I saw a Bowen therapist to put me straight again having spent all that time walking unevenly I needed it. She also released the tightness in my ankle.
Because I'd spent years walking incorrectly on that foot, the side of my foot and ankle are the main problem as they get used to being used properly again so I'm wearing a tubigrip support on my ankle at the minute.
But all in all the operation went well and I'm pleased I had it done.
