Hi and thanks for the query.
It can take up to 6 months for the vitamin B12 related peripheral neuropathy to subside. During this interim, the physician can put you on nerve membrane stabilizers like Gabapentin or Pregabalin.
Other than that I hope other causes like calcium deficiency, hypothyroidism etc were ruled out. Also, although this does not sound like MS related, but a Neurology consultation will be beneficial.
Let me know if you have any other queries.

Vitamins especially the B complex of vitamins play a pivotal role in our bodies. Vitamin A, C, D, K are also very important.
So, deficiency of a vitamin can cause very serious adverse effects as well.
I do not think, you should continue the injections if the course has been completed. A repeat vitamin B 12 levels test should however, be done at this point in time to see if the deficiency has been replenished.
For now, the best course of action will be to optimize your diet.
Vitamin B 12 injectons can cause muscle weakness to a certain extent, but not twitching.
Thanks for reply,
No symptoms does not get worse but it decreases. You might perceive it worst when they come back after symptoms free period.
