I have really been struggling lately. My blood tests came back as possible borderline low on B12 so I have another test next week. Has anyone suffered from B12 deficiency & if so, what were the symptoms? I have been feeling generally unwell, tired, aching heavy legs, lots of other aches, forgetful, not sleeping well etc etc. I know from the past that I have to keep an eye on my iron levels too. Oh the joys!
