Hello, I seem, to be a mystery to my doctors. I have tingling in my finger tips, toes and lips for 2 months now. I had an MRI to rule out MS, blood work ruled out lyme, lupus. it did show that I have a high b6 number as well as a high homocystine and high-sensitivity crp. Dr running more blood work for MTHFR gene and a few other items.
