Hugs SKy,
What they did was wrong on their part.What I wouls do is call your doctor's answering servise and the doctor call you back and explain what happen ,Just maybe the doctor can do something to get you the treatment you need .The thing on your finger was a o2 test to see the oxgen level and where it is. What the hopsital did was wrong, Please call your doctor and hopefully they can get it all streighten out. Thing will work out. I hope you feel better soon .
