I am new here, I was classed as having low B12 (below 500 by haematologist) in February 2017 and I was started on B12 injections in June 2017. I had my second one in January 2018, they are every 7 months, and I have started to notice that the dizziness and lightheadedness I get upon standing from sitting has resolved. However, I have been getting these other symptoms and I don't know why? I also have underactive thyroid.
Constipation
Low concentration, making mistakes
Pins and needles in feet
Joint aches in elbows, hips and knees
Neck swelling
Tiredness
Heavy/painful periods - I have untreated iron deficiency
Tinnitus
Cold feeling to skin
Nails splitting and flaking
and I was wondering if anyone could give me any ideas please?
I am really struggling at work at the moment, it is becoming more and more difficult to keep myself 100% well enough to stay in my job.
Thankyou
