Hi, I'm a vegan and I get a b12 shot every month. A few days ago, after getting my tenth shot my left arm (where I got the shot) felt numb, really numb. Later that day my where I got the shot and up to my my shoulders(both shoulders) turned red (kind of like a sunburn) and any pressure on it stings. I know its not a sunburn since I wasn't in the sun much, just working indoors. Could it be a cobalt allergy? Also I was 3 weeks overdue for my b12 shot (due to work) if that matters. In the past I had gotten allergic reactions but then never had them again to foods such as grapefruit. Please help, any advice on the matter would be much appreciated.
