what should my niece-in-law should do?!

my niece has psoriasis and shes had it since she was 23 and now she is 43. she has two small children and does not work. she lives with me her aunt and mother-in-law. well the problem is she started getting this rash that just took of over night got really bad and she went to one hospital and they said it was just her psoriasis's was acting up and she knew that was wrong. so she went home and had to go back the following morning because it got worse. this rash was on her hands, feet, in her mouth and painful. the other hospital took one look at her and said it could be lupus we need to admit you or you could go home and get worse and eventually die if not taken care of. well they put her in hooked her up to iv's took blood and said they where going to take a skin biopsy. well the docs said the next day that they still don't know what it is and since she has no insurance and no money it would be best if she just left. this hospital used to be the county hospital and everyone went there that had no way to pay. over the years they changed their policy but now both hospital has to give a patient reasonable care no matter what the circumstances. she asked well can she get some of the medication that they had her on to go home with and they asked why you could not afford it. she asked about medicaid and said she didn't qualify. they said that her lupus test would be in tomorrow maybe and she could get the results at the health clinic and sent her out the door. i just think that the hospital did her wrong and how could they send her out the door when she is still sick with this rash that goes from the top of her head to het toes and is so painful she can barely walk. i would just like someone elses opinion. thank you
