Hello everyone, after months on chasing random symptoms we finally got a definitive diagnosis of PA. I had IF antibodies as well as Parietal Cell antibodies. Yesterday met with a GI specialist and they agreed starting B12 injections was essential. She also is going to do an endoscope to ensure my stomach lining doesn't have anything else going on.
So today I was excited to see my family doctor and start the injection process. The recommended 1000 ug weekly for a 6 weeks. I know this isn't inline with the recommendations in the UK, but in Canada they don't have anything solidified so I agreed to start there. Also they only use cyanocobalamin here, so I agreed even though I know Hydroxy is much better.
Immediately following the injection I felt a surge through my entire body and i began shaking a bit. I figured it was my body responding to the B12 so I just waited a bit for it to pass and left after about 10 minutes.
I was feeling Ok, but not great as I drove home and began to notice trouble swallowing and became very dizzy. I pulled to the side of the road and call the ambulance to pick me up. They gave me an injectible antihistamine and took me to the hospital. After 4 hours with no further challenges they sent me home.
I am now meeting with an allergist tomorrow, and my family doctor is very concerned about what to do next.
sorry for the long story, but has anyone else ever experienced this? I am concerned about how to treat the PA if i can't handle the B12.
We are hoping it was just something in the shot, and not the B12 itself.
