How long could this take?

I arrived at Mercy Hospital around 8pm as a direct admission, as a transfer patient, so I should be resting, at least somewhat quietly in a room soon, so I had hoped.  Around 11pm my mom and my sister, who is in the medical field, arrived, exhausted from a long trip, but as anxious as my son and were to find out what was going on.  I finally convinced them to go to their hotel and rest for the night around 2am.   It was 3am, the bells, alarms and ER chatter were just about on my last nerve.  I was still laying on a very uncomfortable ER gurney, when I explained to the nurse that my symptoms had mostly subsided and I asked her if I could please get up and use the bathroom, she agreed to let me walk over to the bathroom on my own.  I came out of the bathroom, walked back to my room in the ER and to my surprise, there it was, like heaven, a bed!  A real hospital bed, with lots of pillows and blankets, and turned down to perfection!  My nurse was waiting for me to come back and explained there were no rooms in the hospital for me as of yet, so I was spending the night in the ER, but she at least wanted me to be somewhat comfy and it was.  I finally got a few hours of sleep, off and on, with all the bells, alarms and codes going off, and let us not forget the gunshot victim that was brought into one of the trauma rooms across the hall from me. Finally at 7am a nurse practitioner from the stroke team came in and explained they were going to do an angiogram of my corroded artery.  Around 10am, they finally came and got me for my procedure.  The angiogram consisted of a needle with a tube attached being shoved into my groin until it finally worked itself up to my artery in question.  That’s when they saw it.  A tiny tear.  Not big enough to fix, but enough to be a bit of an issue.  The tear was on the inner wall of the artery, so there was no real risk of it breaking through and bleeding out, but I was admitted for a few days anyway just to make sure.  I went for a check up several months later and it was discovered that the tear had healed on its own.  No intervention needed.   The strange thing is that these tears are common with some sort of trauma such as a car accident or strangulation.  It can also happen by having your neck adjusted or cracking it yourself.  Who knows?  I’m just glad it fixed itself.
