There is nothing wrong with asking questions, that's how people learn and discover new information that they might not of come across or thought of before. That being said, I think Paley is being optimistic, rather than lying to you. If you feel uneasy with a doctor, just choose someone else. Alot of people feel safe going to Paley and he has a good reputation in LL with other doctors and had good outcomes with countless patients already. With Stryde, you can already walk during first week of surgery, but you will walk funny, by no means normal or natural.
LL is a journey, not a sprint. After the first surgery, there is also a removal and recovery from that as well. You will encounter all sorts of pains and even things others did not because your doctors will be different, your individual bodies' response is also different so healing time won't exactly match another person's.
If a person is the type to have neurosis even after the research they've done, then just forget the surgery because these types will over-focus and everything will bother them. To them, something must be wrong and they will be unhappy all the way and after about their surgery regardless. It is about the psyche of a person going into surgery, you have to be mentally prepared and understand the risks and the trade-offs.
