Oh wow, today I went to the vasc.nurse who informed me about button-hole etc. With hubby, but he could not give me anymore info than I already knew. But I decided to at least start trying to stick my own needles in. And it worked!!! What o doodle. So now I am wondering if it is actually necessary to start button-holing anyway. Is it really that much easier, and or better for my fistula?love Cas
