I feel quite week and exhausted with little exercise. For last 4-5 years, I have low hemoglobin (10.4) and high ESR (90-100). Recently I detected low B-12 (116 Vs 187-880). My B-12 had been also been low earlier (5-10 years), but I did not monitor it. I am 60 years old and have High Blood pressure. My local doctor suggested neuromet tabs twice daily. But I feel I should initially start with injections and then tabs because I feel that my system may be poor in absorbing B-12. Please offer your comments
