What are vitamin B12 injections and how do they work

If the GP is worried about surgery/nurse time involve in alternate day visits for injections (indeed it might not be convenient for you either) you could offer to be taught to self-inject (not as bad as it sounds) and therefore relieve the burden on the surgery

In sharp contrast, someone whose deficiency is purely diet-related might just need a short series of shots to replenish their stores before they can switch to high-dose oral supplements

You will have to consult your doctor if you experience any side effects
