Whenever I get my B12 injections, quite alot of the liquid comes back out of the hole they injected it into. When I got my injection last Friday, I came home to find a large patch of pink/red liquid on the sleeve of my t-shirt. I'm allergic to plasters so they've not used anything to cover the injection hole and said it's fine, but I mentioned it to a different nurse today and she said they should have been pressing the area with cotton wool and putting surgical tape over it.
So, I'm wondering if any of the actual liquid managed to stay inside my arm and do what it's supposed to.
Has anyone else experienced this?
