B12levels after 6 loading doses

by Margaret
(Wales UK)

My initial B12 blood test was 136 pg. I have had 6injections and it has risen to 606 is this a metabolically useful level. My GP has stopped any repeat 3 month injections

I have undifferentiated connective tissue disease and my ferritin levels were also low.

I was very short of breath pre injections which is better but I have peripheral neuropathy and I am getting very fatigued again. During the injection I felt that the peripheral neuropathy was slightly improved and also an urge incontinence of urine that I also suffer from
I am having great difficulty walking. I also have a sore tongue and sore angles of my mouth

Could the reading of 606be a false reading. The GP is not open to any discussion on the subject so I am left in limbo

I would be grateful for any advice
