Hi...I Was Recently At An Urgent Care Facility D/t A

Hi...I was recently at an urgent care facility d/t a migraine that didn't respond to a nerve block or a 4 day course of steroids. My neurologist wanted me to receive IV meds & fluids. However, 3 nurses tried 7 times to start an IV...either they couldn't find a vein or when they thought they had it started, my vein collapsed.
I went for an MRI with contrast the week prior to this and they tried 4 times to start an IV and couldn't so I had the test done without contrast. I am 48 yrs old, I am not an IV drug user (or any kind of drug user); I do not have cancer; I have always been a "tough draw" but never like this! I started Botox treatments for my migraines back in September 2016....do you think this could have anything to do with it??
