Wow, sorry to hear such bad news. Wishing the best in healing and wellness. I am reminded how, precious and temporary, life can be.
Best thoughts and prayers offered. Glad to see a caring community respond in a time of crisis. I've heard of people recovering from possibly worse using alternative means, but I don't claim to understand her issues, but understanding can help lead the way toward recovery, so I wish that for you as well. It's a mystery, I suppose to the doctors. How many opinions have you had, and have you tried alternative choices, because sometimes they are to be preferred, sometimes having safer and more effective treatment.
My biggest concern, is to share that I care and am sad for your pain. As for the rest, respond or ignore if you wish as I just got censored for sharing alternative view, and the last thing I want to do is repeat that offense. I just sincerely have seen alternative methods do better and it might help here, but it might not. If it helps, that would be awesome. I think that's what we all want, so please just take it for what it's worth. Toxicity and metal, in the body, can cause these sorts of unusual symptoms. Maybe PM me if you would like more info.
Best wishes always.
