I was diagnosed with PA 5 years ago (For anyone interested my story is online in the old Pernicious Anaemia Society site.) I haven't worked out yet how it all functions since it became Health Unblocked.
After I developed PA I couldn't find a doctor who would believe me despite the fact that I have a strong family history of the disease and my tests all pointed to the diagnosis of PA. Eventually I saw a gastroenterologist who confirmed the diagnosis but by this time I was so stressed by the doctors who refused to believe me and didn't understand anything about the disease that I developed Generalised Anxiety Disorder and ended up under the care of a psychiatrist who tried every drug available but I couldn't tolerate any of them as they all caused horrible side effects. Eventually the psychiatrist told me she couldn't do any more for me and I should see a psychologist whom I have been seeing for 9 months and I am slowly improving.
When I developed PA I also developed chronic pain in my thighs and despite every possible test the doctors can't work out what is causing the pain. The psychiatrists believe that it is caused by my anxiety but I'm not convinced. My own GP (I have a GP now who has a strong belief in the efficacy of B vitamins) gives injections containing all the B vitamins and that seems to be helping.
My question is: Has anyone else suffered similar experience in conjunction with PA and if so, how often do you find you need an injection?
In many ways my experience resembles Andrea M's, though less severe, but I also had a spinal injection when they were very new here in Australia and my memory is that that was the reason for Andrea's physical problems.
