Man that sounds really bad, sorry to hear. As others have said amputation/removal of the gangrenous tissue is the standard procedure I think, but I'm not sure how that would be performed if it's on her back.
It worries me that she is in a lot of pain, make sure she is prescribed stronger painkillers, probably opiates/opioids to ease the pain - I can't imagine anything worse than being on my potential deathbed in agony.
All the best.
we give her painkillers regulary, she can't even eat anymore
there's a tube going trough her nose to her stomach, we got some fluids at the pharmacy we use as food to inject in that tube
same goes for water
I swear, if she didn't get gangrene she would live at least a 100 years
They thought she was going to die a lot of times, and every time she got trough, she was always stronger then people thought
And when I look at her, I think she's going to recover because she's a fighter, but when I look at the wound..
it's like she was shot with a shotgun, I know she's not going to make it
it may sound bad, but if I took a picture of the wound, you would know what I'm talking about..
