Thanks all, I seem to be alone here on this one, I have no idea why the surgeon told me to do it this way and I'll ask him when I see him early January. My surgeon was Professor Peter Haertsch.
He was quite unclear in hospital when he told me how to dilate, he said he expected I do it half a dozen times a day, and he also said every hour - which is confusing because those two are not the same, but a nurse who told me she dealt with many doc Haertsch's patients, she said to me the clearest he has ever been on directions is to put it in 3 times in one session, and then the next dilation to be 2 hours later, which freed up my time so much more than every single hour!
However this was still putting it in each time for only about 10 seconds, which is weird BECAUSE the booklet of the dilators said to hold it in for over 10 minutes AND the booklet HE GAVE ME regarding the surgery, written specifically for his patients, also says to hold it in for about 20 minutes, with intervals based on what the surgeon suggests or if it is too tight the next time shortening the intervals. We emailed him the day before xmas eve because I badly needed some painkillers, and anyway his reply said I can start dilating less, with intervals of 3 hours, so only 5 or so times a day.
Still unsure tho if it makes a difference? Any thoughts? Will it close over if i dont hold it in? Why is his booklet different to his instructions when he wrote the booklet?
