Hi there. Heard about what you refer to as your "dead foot". I assume you mean "numb"? If so, I can relate, as I came out of surgery, which was otherwise successful, with total numbness in the foot on the operated hip side, as well as the very annoying 'pins-and-needles' & burning sensations that accompany nerve damage. The rehab people called it everything from neuropathy to foot-drop, & I was miserable & demoralized, never anticipating anything like this. Because this greatly impeded my mobility, I spent 6 weeks in in-patient rehabs, building leg strength & learning to use that foot.
You are obviously far ahead of where I was, given your reports of long walks & considerable activity. It is now almost 9 months since surgery, & I am much stronger & have gained a good bit of feeling in that foot, but it has been exceedingly slow. I am still using a walker outside because I feel insecure otherwise, but there has been much progress. All the docs have told me the nerves will regenerate, but that it takes a loooooooong time.
I would strongly suggest you follow the advice about not rushing things... Believe me, you will not get any medals for pushing too hard & can delay your recovery. Take it easy... This is a tough surgery & you emerged from it with what sounds like some damage. Please be kind to yourself. If I can answer any questions, feel free to ask away. If you want to read the sordid details, see my recovery thread.
