what happens if you inject vitamin b12 into a vein Injections at Home - Safety Guide for Self-Administration Vitamin B12 Injections: Benefits, Risks,
Description
Data for vitamin B 1 and B 6 is not sown as no detectable change (more than 5% loss) was observed in the test samples

The most common manifestations include feelings of pins and needles in the fingers and feet , not being able to feel vibrations when they are happening close to you, and a lack of balance (especially with your eyes closed)

My feeling is that if you use any smaller gauge of needle you risk damaging the surrounding tissue at the injection site

All treatments include consultation, injection, and post-care instructions
