Hi, I had a blood test the other day, well, attempted to.. my vein collapsed as he put the needle in, this happened on Monday morning, its now Saturday and i am still feeling discomfort, it feels like theres tape on my arm, or the vein is stretching as my arm moves.. Im too scared to go back to the doctor incase i have to have further blood tests, im petrified of needles. Help please!! What can i do to make the vein back to normal?
