I Was In Emergency Room On Wednesday For A Migraine.

I was in emergency room on Wednesday for a migraine. the nurse was trying to start an iv and made a comment of my veins being difficult because I wasn't eating or drinking and it affected my veins.
then as he was putting meds in iv, i could feel tightness and pressure up my arm, he rubbed it, tried again and it seemed it stopped going in, puffed up where needle was. he stopped. My arm has been very sore. My hand is very bruised, but my arm hurts all the way up to my shoulder, and throughout my forearm. very uncomfortable to move. it is slightly swollen. it is a constant pain, and almost impossible to use it. any ideas
