Yes. They sting a bit. I have found that if I push down on my skin as I'm receiving my shot (which I administer) and I inject very slowly, the sting can be mitigated.
I have a constant low grain pain in my wrist. would a b12 injection help that? If so where would you inject? on the top bottom left or right?
Thanks. Any discomfort in the hours/days following the injection such as nausea or headaches?
