I posted 2 weeks ago about my serum B12 being 602 ng/L and the GP saying my CFS is therefore not due to a B12 deficiency, and that despite me having been on a high dose B vit supplement for 2 weeks, and despite me having many of the deficiency symptoms, including tingling feet and tinnitus.
She said I'd never had a B12 test before, which I found surprising as I'd been along many times with CFS, so I asked for a printout of all previous tests, and in 2008 my B12 was 293 ng/L - in the NHS 'normal' range as I understand it, but borderline from what I've read on this forum. Is this enough to explain my fatigue (which I've had for 20 yrs), and should I ask for further tests to get more understanding of this?
The B supplements aggravated my IBS, so I swapped to patches. Does anyone know if these are as effective as the injections (that my GP refused to give), or should I self-administer the injections? The patches also aggravate the IBS, as well as making the tingling and tinnitus worse. I've read this can happen. Anyone know how long before they start making a positive impact?
Thanks.
