Hopefully they can get to the bottom of what caused his blood poisoning, but not to worry, sometimes they never find out for sure what happened, as long as he is better and stays better, that's all that really matters. When I got bit four years ago by a spider I got the streptococcal blood poisoning, the same that causes the flesh eating disease, my white blood cell count was extremely high, probably why I got well so quick and ran out of that hospital in five days, doctor couldn't understand for sure why or how I got better so quick, I think it was my superior diet high in saturated fat, (I eat lots of coconut oil), still do, large amounts each day in my coffee, I believe coconut oil is why I recovered so quick, Sissy you will have to look into Coconut oil, you can buy it at heath food stores and some supermarkets in the "natural organic sections". While the doctors tell you coconut oil is bad, they give it to you in the Supplemental Nutritional IV bags, (ask his nurse to read the back of those IV bags and you will see it is in there) cause it's the only oil you can directly inject into your blood stream cause it's almost identical to your blood plasma. Most people don't know this but coconuts are NOT a nut, they are the worlds largest known seed, and it is almost impossible to be allergic to coconut oil!
My hubby never listened to me and hated the coconut oil and hated vegs, now he is changing his ways, I'm going to make him fresh vegetable juice everyday when he gets home and slip the coconut oil into the soups. You can't force people to eat better, they have to want it, and now he wants to try which makes me happy.
