Just a suggestion from the. last 12 years of dealing with my wife and a serious illness and being a caretaker.
Four major surgeries, chemo, surgical drains, infections complications, you name it
If your wife is as sick as your saying, to the point your asking for people to pray for her
If your wife is NOT improving, if she is still losing weight, getting weaker, not eating, if in fact you think she could be getting worse.
Get off the internet and take her back to the hospital asap, as in now
I have. no idea were you are located but you may need to go to a larger hospital in a bigger city were there are more and better facilities and access to more doctors
