usually bruise the heck out of me and can only get it out of my left arm in one particular spot... Apparently I have an excess of thingamajiggies in my blood vessels that interrupt the flow and cause the needle to wind up empty... so they have to stick me again... But that one spot doesn't have all those excess valve like things...... and my poor hands have gazillions of microscopic scars from needle pricks for intravenous feeds so there's NO hope of getting an intravenous feed there... They have to stick my wrists... and that HURTS... OUCHY MAMA...
