I have PA and I normally have B12 injections every 10 weeks. I recently discovered I've accidentally missed a dose (there's a lot going on in my life at the moment).
I've got an appointment for an injection on Monday - it's almost 20 weeks since my last injection and it's therefore almost 10 weeks overdue. I'm getting symptoms again after years of good management – the tiredness started a couple of weeks ago and now my memory and concentration seem to be affected again.
Should I see my doctor and request a second injection to make up for the one I've missed? Or is resuming the 10 week routine enough?
