I started having tingling, numbness, burning pain and doctors thought all the usual pathology like MS. I had MRI, blood
testing, ect... and the only thing off was B-6 levels
were 136! I went off the vitamins and then found I was pregnant. It took about six months for me to become "normal".
then, during my postpartum, I started taking a low dose prenatal vitamin b/c I was feeling that nursing was draining me.
