I was diagnosed with PA about a year ago. I had the initial loading dose of 6 injections of B12 in 2 weeks and then continued with regular injections. I found my level to require a B12 injection every 8ish weeks. I had to change doctor a couple of months ago due to moving house and had my first routine B12 injection with them 5 weeks ago. A few minutes after that injection, i suffered anaphylactic shock and so the doctor has said that i cannot receive the injection anymore for risk of another reaction. Unfortunately though, he hasn't been able to decide who to refer me to see in order to establish an effective course of treatment for the future. I am getting panicked now cos the weeks are ticking by and I am feeling worse and worse. I haven't felt well at all since the last B12 so not convinced it actually worked at all. Anybody know who I should see?!! Also, is there a possibility that the injections differ between surgeries and that there could have been something else in there that i am allergic to that wasn't in the other injections i received? Getting so frustrated - don't know where to turn!!
