Tiffany Hedman Medical Emergency

While visiting my family in Philadelphia, I had to enter emergency without any US health insurance.  I have a kidney stone which was NOT removed or blasted because of that lack of insurance.   A stent was placed to save my life because thats all they would do, but no followup ordered for me.  I was told to head back to the UK, only given limited medication, and this was all over 2 weeks ago.   I can not yet fly... too much pain and the stent not removed.  I need the stone checked to see if its still there, removed if it is, and then the stent removed.  The hospital is refusing to finish the work they started without money upfront, I can't get the medications necessary,  and I've lost the value  of my ticket back to London, so I am desperately trying to get the conclusion I need.  That would be the stone and stent removed to be able to get back to life.
