why am i still tired after b12 injections Feel All the Time. Do I Need a Shot?: Shawn Veiseh, M.D.: Family Medicine Chronic Fatigue: Can B12 Shots

Methylcobalamin should not be used in patients with early hereditary optic nerve atrophy (Lebers disease)

Do not inject into a painful or inflamed area

If you know your levels are low, B12 supplements are a great start, but you're going to be playing catch-up, so dont expect things to be back to normal immediately

Those with certain health conditions may also need extra monitoring

In clinical studies, it has been shown to have beneficial effects on skin aging, muscular homeostasis, diabetes, Alzheimer disease, cardiovascular disease, and osteoporosis

I also get pain in my right temple ( I wondered if it were to do with the piturity gland ) but wouldn't say I get it as bad as your experiencing mine is more of a dull ache
