hi, about 2 weeks ago my cat scratched the top of my hand and cut open the vein, got the bleeding stopped, my hand was painful to use for a few days but it had got better, than sunday night i was opening a window and just lightly bumped my hand against the wood shade, i had horrible pain where the scratch happened and every since then my veins are swollen and uncomfortable and roll. i went to the doctor monday and he gave me antibotics but i just dont understand why this happened when it seemed healed and why my veins are so swollen, any help would be much appreciated, the scratch on the outside of my skin looks almost healed up, thanks
