I am new here. I was given a diagnosis of polycythaemia in January this year, and was told I had had it for quite a long time. I had never heard of it, let alone been told I had had it for a long time. I clearly looked it up, and and found this site and have been reading posts from a lot of people since.
I went to my GP because I was SO tired, and had a myriad of symptoms which have been described time and again by many people who contribute to this site.
My GP has been very supportive but has been confused by my "complex picture". She eventually did get in touch with a haematologist in our local hospital who specialises in MPNs. He requested various blood tests in April which included Jak2, erythropoetin levels, and B12. He said the results of these would determine if he needed to see me. My B12 came back as deficient, with a reading of 122 and I opted to start with B12 tablets because I was concerned that my HCT might increase quickly if I had injections.
I recognised when I researched B12 deficieny that many of my symptoms were classic. My GP sent him all the results which took a while as the JAK2 took about 6 weeks to come back
I saw the Haematologist recently and he said my JAK2 was negative and my erythropoietin was "within normal limits", so told me I definitely didn't have pv, but he was ordering whole body scans to totally exclude secondary causes. He also said he wanted me to have injections for the B12, and would confirm that in his letter to my GP.
I have to admit that I am confused. Does anyone else have B12 deficiency with polycythaemia? If so, did injections increase red cell production?
