Newbie here! Apologies for the long post - I don't know who else to ask!
I have been diagnosed with iron-deficiency anaemia on and off all my life, from toddler age onwards. I don't know that my B12 levels were ever tested.
I read about B12 a few years ago and started supplementing randomly, thereby invalidating blood tests...
I have been told I have an auto-immune condition, probably Sjogren's, but I have had a bad back, (surgery to remove ruptured disc and 4 further herniated spinal discs)neuropathy and weird tingling and zapping sensations etc for many years which has always been attributed to the back issue.
I was told I probably had Chronic Fatigue Syndrome about 15 years ago.
I have been having serious stomach issues for quite some time but no doctor investigations were carried out because I refused PPIs and a gastroscopy.
I have had constant dental problems for the last 6 years or so and each time I get an infection (which ends up with an abscess and tooth extraction) I feel VERY sick.
The nausea and vomiting for the last 6 months have been horrendous.... and I am now so tired with brain fog and concentration issues that it's all I can do to go to work. I'm exhausted but don't sleep well.
I gave myself a sub-cutaneous injection of 1ml hydroxocobalamin in the morning, 2 days ago, and have barely felt queasy since!!! I was full of energy that day and thought I had more feeling in my leg. However, whilst still not feeling sick, which is HUGe and the first time in months, I am today completely exhausted again.
My grandma had PA and I know it can run in families so I've ordered a private blood test for Intrinsic Factor antibodies and an active B12 test.
My question is: would the fact that the injection stopped the sickness, which nothing else has done in months, indicate that I could have undiagnosed PA?
I appreciate that if the antibodies test comes back negative (which I understand it often does), any other blood tests won't be valid because of supplementing but I am quite prepared to self-inject if I have to if it makes me feel human again!
Does anyone have any comments or advice they can offer, please?
