Hi Stacy;
Some labs only include ranges up to 1200. I've only been to 2 labs. The first one showed that I was above 1200. The second one showed that I was above 3000. Some labs will measure even higher. The highest number that I've read about was in the 800,000 range.
It probably means that we have some sort of a transport problem. I'm not sure how to repair this.
Neuropathy is strange because it comes and goes, and the sensations vary. There can be tingles and shocks along with vibrations and numbness. At one time, 5 yrs. ago, I had a large numb patch on my right side just below the liver. It felt like a piece of leather was glued on. My skin there seemed foreign. I had shocks and vibrations that traveled down my right hip to my foot. There were weird sensations all over my body. I had trouble controlling my hands and feet. I was falling regularly.
I tested negative for Pernicious Anemia. I didn't have the anemia part, but I had enlarged red blood cells.
These past five years have been challenging because neither myself nor the Docs I've seen knew how to treat this. So I've been bumbling with taking B12 in fits and starts. I would get better, and then take less of the B12, thinking that I was fixed. I also didn't realize that so many of my symptoms were B12 related.
Now I take it every day, without fail.
Numbness means that some serious damage has occurred. It can take many months to heal. For me, it took a year for most of my numbness to heal. I still have this numbness on my heel... maybe it's a reminder. But It's still getting better, slowly. I probably wouldn't notice it much, but I compare it to the other heel to check progress.
So, healing can be a lengthy process, and sometimes painful when nerves regain feeling. But each day gets better.
I'm happy to answer your questions, if I can understand, I may miss things. I know how frightening this can be.
