Hi. I know that breathlessness is a big symptom of B12 deficiency, although I didn't have it at all until I started self-injecting 5 weeks ago.
However, my breathlessness seems to be getting worse by the day, and I had to sit outside in the garden for most of today, because I felt like I had real air hunger indoors.
Is there anything else that could be exacerbating the breathlessness apart from B12D? I did notice that the only day I didn't have it too bad this week was the day I forgot to take my 5mg folinic acid. But that's probably a coincidence?
Any tips gratefully received!
