Hi!
Think we need a few more clues though, eg how long you've been T2 and what treatment you've been using and for how long, what prompted the addition of Victoza?
You need warm fingers to get blood out of them, so if yours usually aren't the simplest way to encourage it to flow is to wash your hands and it doesn't necessarily have to be hot water. Take care to dry them well and 'briskly'. You know the part of fingertip flesh that protrudes either side of each nail? Down the side/back of that bit is where to get the 'bodger' positioned for easier use for this purpose, stay away from the actual 'pads'.
If you can't wash and dry for whatever reason, arm down at side of you and shake that hand instead before bodging.
