Has anyone experienced a bad reaction to B12 injections?
I had a course of injections a few years ago and had no reactions to them. However recently I tried a new course of injections to bad effect. After the 1st injection I felt a little unwell and then after the 2nd one I had a really bad reaction with chest pain and breathlessness which are symptoms which I get when my fatigue is bad.
Hi, I have done B12 in the past. Never did me any good. I never had those problems. But if you are experiencing side effects such as that possbily you should stop doing the injections. You can buy oral B12 at a health food store. Maybe that will suit you better.
