I have had B12 jabs for about 40 years. In SA you used to be able to get them easily.
I used to have the Cyno plus a b complex jab.
In UK I have bought Hydroxy from Amazon De - Rotexmedica B12 Depot brand and take a BComplex supplement.
I am on Cortisone for an autoimmune disease - weaning slowly (currently 8mg). In Dec last year I was hospitalised with pneumonia and had loads of hectic meds.
Since then everytime I have a B12 jab I feel really weird - slightly dizzy, vision a bit blurred, and almost like I can feel it running cold through my vascular system. This has happened 3 X now - I'm scared to try again. It has however happened to me without having a jab too.
Thanks xxx
