evening, my 13 year old sister slammed her finger in the door onJuly 4, it started hurting immediately, my mom took her to the ER, they told her her nail would fall off, the finger is bruised from what she was told which is why it is now black. As of today, it has a smell similar to vomit, we have been putting iodine on it and she has a bandage over it. The nail is partially falling off, she we take her back to the ER? it does have some swelling
