We are off on a natural/social section tangent here- but I will chime in. I also have peripheral neuropathy due to Sjogrens syndrome. Sjogrens/Lupus can go along with ITP . My neurologist has advised B2, not B12 for PN. look it up if interested, there is some research. And Alpha Lipoic Acid 600mg as Mel said. He was very excited about that and I tried it for a month. It caused so much foul smelling gas and abdominal distress that it didn't seem healthy for me, but I may try it again. And YES, a big yes to acupuncture. I go to Community Acupuncture which I love, its a group session and only costs $25 per session. It calms down the neuropathy attack, calms me down, my mind gets quiet, problems/stress goes away and I get deeper sleep. But I get so busy that I don't go regularly. Its something you have to work on, not just a one-off session. I also do another kind of energy work that also calms down the nerves, relieves stress and is deeply relaxing. I do that one every day.
Research from JohnsHopkins has shown that in my disorder, primary Sjogrens, there is swelling/inflammation on the dorsal root ganglia, nerves coming off of the spinal cord, and that causes a prickly feeling from head to toe. So its a bit different from feet neuropathy, or diabetic neuropathy but still called PN.
