What are your symptoms that were cured that you didn't even know were B12 related?

I am still early days, one month in, but I have a couple that I think are notable.

Weird dry patches at the sides of the tips of my fingers. Just a couple of them on each hand. Like dried superglue. They are now super smooth!

Blood pooling to my feet, I looked so hard on reddit for all the reasons for this and never saw that it could be b12 related. This one was instantly cured after my first shot.
