Hi Julie,
I've been having the chin numbness. (Okay, so when I googled it, it made me write a brief will the next day.)
I was also having my left arm be so numb it was like dead weight.
Mine came at a time of increased stress.
Are you aware of more stress? in addition to the stress from the illnesses, I mean?
Oh, and the leg thing... not so fun.
But.
For me the chin numbness goes nearly away with a B12 shot... sometimes I need two. And if I don't try to skip a day with the B12 shots, I don't have the arm numbness.
The rubbery legs... that seems to almost go entirely away if I just don't overdo the exercise. For me, a LOT of exercise is to walk around my garden (sort of a big circle) four times.
I was having an extremely sharp pain in the top of my leg, not quite where the hip joint is, and that would make me feel as if I would fall down when it happened.
Then it stopped happening and I was so glad and relieved, and I fell down twice that week. (unexpectedly, for no reason that I could identify. I just lost my balance.)
But, I am SOOOO lucky, because the first time I fell into an iGourmet box that I'd saved because it was sooo cute: it was lined with styrofoam and was like a little cooler. It was, of course, actually meant to be a little cooler. And then the second time I fell going through a doorway, so that time I had something to grab onto and again did not hit the floor.
I've had a lot of different experience with nerve problems: I was "profoundly" deficient in B12, then I lived in hydrogen sulfide and thought my B12 deficiency was getting worse, only really it was the hydrogen sulfide, then I got tetanus which is a central nervous system disease.
For all of these things B12 was significantly helpful.
I have B12 shots because they are highly cost effective.
You can try B12 by getting the Methylcobalamin lozenges. I would get the 5mg ones and take three a day (dissolve under tongue) for a week.
That would sort of be the equivalent of being started on B12 replacement therapy.
And, Extremely Important: keep notes on your symptoms, the amount of B12 you have... and any daily changes.
That way you can see if it helps. I believe it is likely to help.
Vitamin B12 is a highly effective vitamin, so you will feel results in two to three weeks or less. If you don't... I mean, I can't imagine what it could be where you would not feel results.
