So, about a month back, i got my b12 tested and it was 130pg/ml (normal range - 180 to 900) I had all sorts of symptoms, tingling, extreme fatigue, no mental energy at all. So I was put on Injections. Soon after my 3rd and 4th injections, I noticed the next 3 days are terrible. So much weakness and fatigue, body ache, tingling gets even worse.
So I'm not able to understand what's happening?
Does it feel like that initially or has the b12 has overdosed? Should I quit the injections? But then again, My initial symptoms are still there.
