Hi @bevvzy, I was told the same thing. I wonder what women do who have had lymph nodes removed from under both arms. How do they have blood pressure taken or give blood??
They have to tell us all the possibilities however unlikely.
I was a plasma donor until my breast cancer diagnosis and have a great vein in my left arm which theoretically I can no longer use for blood tests. But having no usable vein in my right arm I have no choice. For my last blood test the nurse used a very fine needle and a syringe to draw blood and it was fine. She said it was more about guarding against any infection at the needle site.
I just find myself being a bit more mindful of cuts and scrapes though as a knife wielding lefty I am more likely to cause danger to my right hand!
Hope you are doing OK. Jane xx
