If there is anyone who might know about the effects anaemia has on the heart I would be very grateful for advice. Ivehad acute anaemia for two years and am on my 3rd week of B12 shots which has got rid of my pins and needles. I am still having heart pains though and they are more frequent. They are sometimes quite sharp and sometimes quite dull like its being gently squeezed. My iron count was 1 and my ferritin count was 2 at one point so my anaemia was severe.
When I get my B12 jab I can actually feel my blood circulating - is this normal?
