perforated appendix

Hello,
I'm sorry to repost a question that has probably been addressed somewhere on this forum. Please bear with me. My 30 year old healthy son ignored his body and ended up with a perforated appendix being removed a week and a half ago. Having been in great health all his life, we've never needed to think about alternative medicine. Now he's a product of mainstream intervention and I'm worried as hell. He's already suffering from post-op infections, had a drainage tube inserted (now removed), but the surgical incision is now infected. It's been reopened and packed with gauze to "heal from the inside out". He's having severe night sweats but no fever. Taking Antibiotics , of course, but will end those in a couple of days. I've tried to NOT imagine lifelong problems for him related to this health issue, but I can't shake the worry. So...here I am asking for sound advice on dietary and supplemental suggestions for supporting his natural immune system to take charge and get on top of this thing before going down the mainstream path much further. No fearmongering responses, please. Thanks for your help. Tweet
