All of the above good advice, and get a wii fit if you can. Someone else had posted how it helped their balance and their core strength. It's true.
I have a strange sensation that I'm walking on uneven, stony ground under my left foot and my right foot sort of turns inwards to compensate for it. As you can imagine, it's making walking tricky at times and I've had quite a few falls lately. I fractured my pelvis trying to get on a train in September and seem to have fallen at least a couple of times per month since.
Despite the frequent falls, my pelvis has healed and I'm now trying to step up my exercise a bit. I figure Pilates will help, with its focus on core strength, and I'm doing yoga for balance. I'm swimming once or twice a week, lots of breaststroke to move my legs and pelvis through a wide range of motion. I'm also walking lots but I have to pretty much talk my way through each step to 'do it right'. I'm reluctant to use a walking stick, as I always feel bent out of shape when I do, with all sorts of aches and pains that weren't there before.
I hope you're doing OK now xx
