question: Hello doctor, I have had macrocytosis for a long time. My last B12 and folate levels were high. I have symptoms of nervousness, snarkiness, light headedness, palpitations, and sometimes tingling in the hands and feet. It is making me crazy. My MCV is 104.9, MCH 35.6 and last TSH 2.18. I have consulted many doctors but they do not think there is a problem. Can you help?
