Not being strange at all
Actually very good question.
My right arm is still "fairly"" normal, so I do allow BP tests on that one.
But, both arms (arnd legs) are stricly out for blood draws. For me, I am fortunate in that I have a chest port. All draws, chemo, IV's etc are run through that.
Once, when they couldn't get it to work, they acatually took blood out of the jugular.
now that was quite an experience.
There are wrist-band BP machines now that are available that have much less pressure then the old style used in the upper arm. For some, those have been safe to use.
I think it pretty much depends on the state/stage of your LE.
Sometimes, too, you have to make exceptions. When I had my lung procedure done in January, the docs insisted that in case of life support means etc, that they also have a running arm IV. It was a tough decision, but I did let them use my right arm....but...only for the duration of the surgery.
