Hey so I had low b12 and somewhat low iron. They thought it was causing my symptoms (all over body pins and needles, internal tremors and muscle spasms).
So I took high doses of b12 twice daily, and also took a multi vitamin in case I was deficient in other things.
And I felt like my pins and needles were getting better. At least I was able to sleep at night and some nights the pins and needles were very mild. But I still had mild internal tremors/ vibrations.

Not long after my symptoms changed and I experienced fatigue and weakness along with internal tremors /shaking but my pins and needles remained mild.
New bloodwork revealed my b12 was now very high and my iron was now on the low end of an optimal range.

So i started taking iron (which I thought was responsible for alleviating my weakness the first two days, but it could have been something else that I was doing too for example I also started electrolytes and just eating a well balanced meal with the iron and it seemed to stop my abnormal fatigue and weakness). But each morning I’d again wake up weak.

And I stopped taking high doses of b12 because my blood work read high in it, and just took the multivitamin instead, but the same night my pins and needles came back worse.

And my doctors are no help. So I guess I’m just wondering is the fact my b12 is now high from taking high doses every day mean that my liver has finally absorbed enough? Should I assume I’m no longer deficient in it??? Or could the b12 vitamins I took that day just been in my blood without actually storing in my liver, and thus making the high reading in the blood test not accurate ?
And since my vitamin b12 blood levels are high now, i should assume I’m absorbing vitamins just fine???
And if it’s high should I still take high dose of b12?
Because I thought I could stop yet my symptoms came back fast. Is maybe my body depleting my vitamin stores really fast or something?

I’m not even sure if vitamin deficiency is causing my symptoms maybe it was just a coincidence my symptoms seemed to get better when I started taking them.
But my doctors have never explained to me how this works.
They told me to take high doses of b12 for a month. Yet it’s been less than that and it’s reading high.
