| Thank for your support guys, I am feeling alot of relief today and am getting bloodork done thursday. I am taking 3 5000mcg b12 vitamins sublingually, making my urine appear an intense neon yello. The thing i am desperate to find out is if this sudden neuropathy could be caused by kidney or liver failure. I kno alcohol can cause neuropathy too. The suddeness of my symptoms have made me really nervous that i have a major, specific problem causing this besides my heaviness, non stellar average blood sugars or inactivity. Is it possible that liver or kidney failure could do this so quickly? |
