Of course I took my cane to do the shopping; I take it everywhere now. The best thing about the cane is that it's so much easier to walk with it - I had no idea that I was in as much pain as I was and that I was struggling so much. My hip and leg hurt so much less when I use the cane that there's no way I wouldn't use it now. It just feels so much better to walk with it. Using the cane is starting to feel natural and I'm feeling less self-conscious with it as well.
Thank you all for your emails and support about my cane - I really appreciate it. It's good to know that I'm not the only younger (well, young-looking in my case) person to use a cane. And that using a cane isn't that weird or anything.
