You need answers from Brassard patients so that you are evaluating the same technique - even then, the problems and the healing vary from person to person.
I had my op in the UK by Mr Bellringer. (simple inversion)
I was on my feet the day after the op and walking about a bit....... 4 to 6 inch steps LOL and tiring quickly.
By the end of the week after the op, I was walking reasonably well, but very carefully.
I took it easy for another week, gradually walking more.
NO LIFTING OF ANYTHING
probably a month before I could walk fairly normally
