Hi! Again. I'm in a bit of a pickle and would love some advice. I started displaying neuro symptoms and started alternate day injections of 1000mcg. My B12 skyrocketed so I cut down to two injections. Symptoms returned so I've begun 0.5mcg hydroxy for the past two days. Some symptoms improved but persistent pins and needles in both feet, shooting up my knees. I'm worried. My supplementation brought my folates up but still have low iron (on capsules). Is the B12 working? I posted blood work in a previous post.
