Why don’t doctors give B12 injection on hand? Give a specific reason except heavy injection or high dose?
Doctors typically avoid giving B12 injections on the hand because the hand contains many delicate structures such as nerves, tendons, and blood vessels, making it a risky injection site. The risk of accidentally hitting a nerve or damaging a blood vessel is higher in the hand, which could lead to complications like nerve damage, bleeding, or infection.
Instead, doctors prefer to administer B12 injections in areas with thicker muscle layers, such as the upper arm or thigh. These sites have fewer sensitive structures, reducing the risk of injury and ensuring a safer and more effective administration of the injection. Additionally, the muscle tissues in these areas allow for better absorption and distribution of the B12 supplement into the bloodstream, facilitating its proper utilization by the body.
