My worst headache ever...

Since Tuesday I have had a migraine. I tuesday night, I got a bad migraine. The ones that after a while you feel so nauseous you vomit. So around midnight I started vomitting. After a while I stopped, drank some water and got some shut-eye. The next morning, my migraine felt like it was gone, but my head still felt a little sore. Like it was sore from being so painful. So I went on with my day with a headache. I started to notice that my vision was getting bad that day, but I didn't think too much of it. Yesterday I woke up and my head felt even worse and my vision was still bad. I started to also notice that I had pressure in my left ear and other weird symptoms. I called my mom and she said I have to go to the ER. The problem with this is...our insurance only covers the Richland Hospital. So, around midnight I had to drive to Richland Center, about two hours away. So, I got to the hospital and registration took forever. Which to me doesn't sound like it should take 20 minutes for registration in a medicial emergency. But maybe I'm wrong. :/ So, I got into the doctor where we talked about my history with migraines. They gave me the most painful shot I've ever had in my life and a pill for nausea. All the shot did was make my leg hurt as much as my head. I went to bed around 3:00 am. Today, I woke up still will my head hurting. My mom made me an appointment immediately in urgent care. When I got there today, I had to talk to another doctor and get blood taken. The doctor still isn't sure what is going on, because my blood looked normal. So tomorrow, I have to go back to the doctor to see if I need a spinal tap to release pressure in my back and head. I hope I get better asap, because this is the WORST headache I have ever had.
