My
vitamin b12 is 100 and a year back my folate was also low but i never got any treatment. Recently i was facing problem in concentrating on studies, weakness, stomach issues, pain in legs, cold hands and feet and irritability, dry skin so I got myself tested for vitamin b12 deficiency and it was 100. What should be the treatment. Should I take injections or oral tablets and do i need to get myself tested for folate again as it us very expensive. Please advice
