My latest blood results are:
Serum Folate 18.36 ug/l (>5.38ug/l)
Vit B12 680 ng/l (211-911ng/l)
Active B12 151 pmol/l (25-165 pmol/l)
Serum C reactive protein level <4 mg/l (0-6 mg/l)
Serum Ferritin 96.9 ug/l (10-291 ug/l)
I was taking 6000mcg oral B12 for a few months and stopped taking it 3 months ago. I have the usual symptoms. 27 year old female. I have been in a lot of pain so was given strong codeine but I don't like to take it. I was referred to a rheumatologist and diagnosed with fibromyalgia. I am now on 10mg of amitriptyline. Been on it for 2 1/2 weeks with worsening symptoms.
Are these results normal after taking high doses of B12? Should I go back to the GP and push for B12 injections? Start taking the oral B12 supplements again? Or should I give up and accept the fibromyalgia diagnosis?
Thanks for your help.
