Signs of a severe allergic reaction (anaphylaxis) include: Skin rash, hives, or severe itching Swelling of the face, lips, tongue, or throat Difficulty breathing or wheezing A rapid heartbeat or a sudden drop in blood pressure If you ever develop swelling of the face or throat, trouble breathing, or other signs of a severe reaction after any injection, treat it as an emergency and call 911
I do think a drip of B12 straight into a vein continuously woukd benefit and eliminate alot of the rollercoaster of symptoms Any treatment can give side effects/ symptoms
However, as with any injection, there is a risk of side effects such as pain at the injection site, infection, or allergic reactions
Additionally, it aids in preventing and treating some forms of lung cancer
IM stays elevated for slightly longer at the injection site
This means that B12 injections can rapidly increase B12 levels in the body, providing quicker results for athletes
