I am not sure as to how you managed to severe the veins in your hands, but I feel that a visit to the ER is indicated since the blockage of vein drainage can lead to increasing swelling that may worsen. Worst case scenario, they will have to stitch them back, best case scenario, they will ask you to do what you have been doing, pressure bandage and limb elevation,
do remember to accept the reply if you find it useful,
