OK i have a riend that is new to the world of Iv drug use and has had some trouble for the 2 months he has been using this way. his veins are small and deep and have he has had a few misses. he has a knot that is hard on his vein where the crease of his elbow is. he has used this vein pretty often cause it is the easiest on my friend can hit He also reused his 100 cc needles several time and said it kinda was hard to pull out and one time .does anyone know what is wrong?
