Lululucy, In the Uk they are rewriting the protocol and we have been told within reason not to worry too much regarding the 90 deg rule, I use the helping hand to dress and it’s fine can get loose trousers on and knickers no problems. We have to wear knee high ted stockings for 6 weeks post surgery and they need changing every other day which is a mission but hubby has that chore . As I’m sure you will read on the forums often the worst part is sleeping on your back and I can only manage a couple of hours at a time so it’s a long night try not to worry, take all the help you are offered and keep reading, in the Uk we are not told of the pain or swelling that is normal or the fact you cry for no reason so comes as a big shock, the better informed you are allows you to cope with the situations when they arise and not be scared.
This is a great forum whatever country you live in, so much support from people who have been there and done that..... good luck will keep an eye out for your post on the recovery side soon
