I just had my second B12 injection this morning after being diagnosed a week ago. My level was 194. I had pins and needles in my hands and burning feet, mind numbing fatigue and shortness of breath.
My symptoms now seem worse than before, but I have read this can happen initially with the level being brought back up to normal. How long does it usually take to see positive results? I am also taking 1000 mcg's orally, with a B complex and a multi-vitamin.
Any replies would be appreciated, thanks.
