Joining the group I think

Hi there! I've been experiencing weird sympthoms such as the following since last month:

• Some level of fatigue (such as having my arm tired of typing) which I believe it was tendinitis somehow with the traumatologist
• Lately tingling or numbness in some of the arms or hands, for example flexing my arm for some time feels like "irritating my nerve" in the arm or sitting in the desk causes my paresthesia in the feet (either one or another feet)
• Some level of "depression" I would say as well

These were the most notable among all of my symphtoms.

I checked my old blood test from January 2025 compared with the one recently did and I got the following:

• Jan: VITAMINA B12 - CIANOCOBALAMINA PLASMATICA 399.00 pg/ML
• Jan: ACIDO FOLICO SERICO 7.8 ng/ml
• Jan: VITAMINA B12 - CIANOCOBALAMINA PLASMATICA 303.00 pg/ML
• Jan: ACIDO FOLICO SERICO 5.9 ng/ml

I started to take glicinato de magnesio like a week ago and I saw a lot of improvements since day 1 but not entirely cured. And I was wondering if these two Vits can have something to do with my sympthoms since they are not entirely gone and mentioned values dropped.

I wanted to wait to see again my doctor but I would like to start to feel normal from now so I'm curious and got this reddit here.

Would like to hear some opinions as I read some experiences. The guide seems to cover a lot of things and I can relate some stuff mentioned there.
