I believe I have been under treated for pernicious anaemia for many years and last year decided to try self injecting.
I decided to go with sub cut as I figured it would be easier.
I noticed I felt quite unwell for a few hours afterwards and it put me off so didn't bother again but I feel so poorly I do feel like I need more b12.
I decided to try again this time
Doing intramuscular with the help of my friend who was a nurse.
Straight after she did the injection I felt really weird as if I had loads of adrenaline running through me.
I felt weak and shaky.also flushing i my face.
I still feel a little wonky now although not as bad.
I got the b12 fr Germany as suggested by somebody on the forum.its b12 depot rote medica hydroxocobalamin
I was just wondering if you can be sensitive to different brands of hydroxo?
I've been having my injection every three months for the last 14 years and I've never had a reaction.
Any help would be much appreciated.
