What I meant was after poking must compress the vein puncture site. So that dont form hematoma. Big blue black swelling. Blood leak out of vein into soft tissue for swelling. Very jia lat. No good for patient.bro my viens is really big u know like those electrical wires my wife said if only all patient got my type of vien every nurse want to do me bro!
and if the foreign doctor do compress i am sure my vainexpend and super easy but like u said maybe that day i got a newbie doctor very suey for me bro kekekekee.
