Thanks Glenn. Do I have to drain like half by blood to do all these tests?

Will I have problems getting the doc to request all these tests? I have to go in and get my thryroid tested again (I'm overdue) and was going to throw at least the B12 on while I'm doing that. My Endo isn't going to want the results from the other stuff, but I would like to recheck the B12 sooner than later.

What's the skin punch biopsy like? I've seen it talked about a lot here, and the Neuro said he assumed my EMG would come back normal, and no, he hasn't ran any tests except a basic blood panel. Can you ask it to be done on one leg and not the other and do they have to be on the same side? I have a big tattoo on the side of my right thigh (BTW those nerve meds make getting tattoos really easy) and one on top of my left foot. Both are right where this tells me they'd be: http://www.nynapc.com/procedures/skin-biopsy/ Of course I only have three tattoos, but they're right where I don't need them for the biopsy.
