Hi KPPurple
I would look at the Guide to PIP Claims and Reviews, which has been updated since you last submitted a form, and look through each of the questions again, particularly to see if there are any areas where you need to strengthen your answers. I say this because as soon as the DWP knows you are post-surgery, they will look to say you are 'better', so emphasise that, despite the surgery, your condition remains largely unchanged, and explain why.
There isn't a sample of a completed form.
