After the first outbreak they eventually cleared up - at that time my surgery stopped my injections

Can everyone have an IM shot of B12

While vitamin B12 injections are generally safe, some people may experience mild or temporary side effects: Redness, swelling, or mild pain at the injection site Dizziness or lightheadedness shortly after the B12 energy shot Nausea or upset stomach in rare cases Mild fatigue or feeling tired right after the vitamin injection Headache or brain fog (usually temporary) Mild fever Allergic reactions (rare) rash, itching, or shortness of breath Low potassium levels (very rare, but can happen with frequent vitamin shots in deficient individuals) Ready to Feel Like Yourself Again
