Reported but rare: I've given B12 shots to hundreds of patients and have never seen this happen so I was going to say no, but in researching this some sites list "feeling of swelling of the entire body" and "swelling of the ankles or feet" as possible side effects. This is very rare. https://www.drugs.com/sfx/vitamin-b12-side-effects.html and https://www.medicalnewstoday.com/articles/318216.php See comment:
