April 30th update:
Hi Everyone! I visited Dr. Ferkel yesterday and things are healing on scheduled as expected. As far as the ankle brace goes, I only need to wear it as needed. I can stop using it during physical therapy, which is a big plus because there were limitations as to what I could do while the brace was on. He also said to use it if I think I will be doing a bit of walking. But it's really subjective - I have to decide when I need it and don't need it. I also brought up the pain near one of the incisions. He said it's from the surgery itself and will go away. The pain has lessened each day, so he's probably right.
On an interesting note, I mentioned this web site to him and he plans to take a look. He did echo one word of caution, and I think he's right despite what his intentions might be. Sometimes we give medical advice, even in subtle ways and not realize it. A simple example is, "Denovo didn't work for me, so I don't think you should try it, " and vice versa. Success and failure stories should not influence an absolute decision, but instead should always educate us and push us to seek out more information from the trained professionals. But what I've found to be really useful on these forums is the referral of doctors, and I'm even more glad that Dr. Ferkel has been mentioned as one of the best surgeons for this Denovo procedure.
Anyhow, when I go out for the day I still wear the brace mostly for protection and support. I'll see where I stand next week and decide whether to continue wearing it or stop. There will come a point where the brace needs to come off to aid with recovery.
