Was it exactly the same spot as where you had just taken the basal? I can't imagine it making much difference if not, though I suppose you may or may not have a different absorption rate in your leg to where you normally take your bolus?
When I was on a basal bolus regime, I didn't hae specific spots for basal and bolus, I just tried to rotate them....
Happy to be corrected if others have different experiences.
Personally I don’t have a particular body part for a particular insulin it just goes in wherever is nearest to my hand at the time and with this quite laid back attitude it’s amazing that I manage to rotate my sites but I do so must be some method in my madness
