If you are a chronically sick person you may have some idea what 20G means. I went to the ER on Thursday. They needed to get a 20G IV started so they could run a very important test to make sure I didn't have a blood clot in my lungs. They tried 13times to get on started. They even brought in a sonar machine to get look at deeper ones, which still didn't work. Ended up not being able to do the test. They had other tests that can do about the same thing. So... all that to know that I have HUGE bruises all over my arms. I look like someone beat the crap out of me or that I could possible a junkie.
Having chest pain is so much more complicated. It can't just have pain. Now I have visits to the ER, with lots of poking and more pain. It's really scary to have pain now, it could be something really really dangerous. Like I was told by the ER dr, we have to work you up like an old person, and consider everything. "With your history....". At 28 I have a history, yippie. Now every pain is a 10hour adventure at the hospital.
