I decided yesterday, after my Vitamin D helpfulness/relief from "ball and chain" leg cramps that had been going on since 2/6/13 fairly continuously....

that I'm going to try some Vitamin B-12.

Also I read what Wings said in the sticky thread.

I have all over itching, tingling, mild pricking that some might call Skin Crawling. To me it's between a tingle and a prick which makes it a pringle - can only joke about that 'cause doesn't happen to be annoying the heck out of me right now and bringing me down. Basically, it has qualities of the foot tingling and prickling, but it's all over - trunk, thighs, arms, upper and lower, back, yada yada. (Note: it has very similar qualities to the foot tingling I've been having since summer, therefore I suspect Neuropathy related)

I have had no tests since I've been seeing a neurologist for five months now except the shock test where it was determined I had a very small abnormality.... right leg (three of my toes went to sleep for no reason, last summer.) Am scheduled for a second opinion first week in April. So I don't know what vitamin deficincies I might have - or how to spell it - except the vitamin D deficiency that was found by an orthopedic doc who was seeing me for Lyme disease.

What amount to take then? I remember years ago I heard about vitamin b12, that it helped with energy, and I carried a small bottle in my purse and would pop it from time to time, no idea how much... and felt a lift.

I know that 5 Hour Energy has b12 in it, so I looked that up, how much: 500mcg. (My use of the scientific method / educated guess ) Bought a bottle, smallest amount was 1000 mcg, and cut it in half yesterday, took it around noon. For the first time in a couple of unhappy days, the all - over itching backed off. This could of course just be coincidence.

This morning, woke up and itch attack was threatening.. that means really really light pricks, firing about all over like firecrackers, randomly, which usually means another day of all over itching is coming for me.

So I thought, let's test it. I took 500mcg of the vitamin b12. To my astonishment , bout 20, maybe 30 minutes after ward, the "itch threatening" backed off. Usually I have to take some of my nightly tegretal (also bp) to get this to happen... then I have to keep dipping into my nightly tegretal all day long to back off the all over itch when it breaks through again. Sometimes I worry that I won't have enough tegretal to get me through the night so I just itch, prick and tingle all over for periods at a time.

I'll let you know how it goes. Any other b12 experiences, please feel free to post on my thread, or related info., etc., as I am new.
