Did you experience muscle atrophy from B12 deficiency and were you able to reverse it ?

One of the main symptoms from B12 deficiency that I had and that bothers me and scares me the most is the muscle loss/atrophy, it's diffuse, everywhere around my body, this weakness all around can be quite bothersome, I try to be active as much as possible, and have recently stated treatment to hopefully heal and reverse everything

But I am extremely scared of this muscle atrophy being permanent,Did anyone of you experience it as I did ? have you been able to recover from it ? and if so, in how long ? I would be really grateful from answers

Also, Thanks for this community, the moderators and the people commenting, the advices and information you give here are invaluable
