Hi all , this is my first post on this site .
Four years ago hyperactive thyroid . After several months of carbimizole I had RAI .
Long story short , started on the Levothyroxine saga with not much success. Recently persuaded Endo to trial T3 which seemed to make me feel worse 😕 .
My question is about b12 .
After dragging myself around , completely exhausted I was started on booster jabs . Every three months I was told .
My bloods in August were 185 ( 190 - 910 )
The next blood test said 547 " "
" " " 1248 " " this was February.
I am feeling unwell so I had a blood panel with Blue Horizon as my next jab was July 22nd and they wouldn't bring it forward .
Phew , just as well b12 a week ago was 1390 ng/L ( 191 - 663 )
Can anyone tell me what is going on. I have had an occasional spray , but nothing regular
Any advice appreciated.
