This is the 1st time I have posted here and would love some advice. I have B12 deficiency and have an injection every 3 months. This I feel is not frequent enough and I usually start to feel terrible about 3 weeks before my injection is due.
However, I only had an injection on the 19th December and already I feel awful. I have pins and needles in my hands and feet, my heart races and I'm short of breath, I feel pinpricks on my head and I feel the worst exhaustion I have ever felt. I had a blood test at the beginning of the week and they are saying it has come back satisactory!!!! How can this be when I feel so awful? It has really frightened me.
Any advice would be really welcomed please.
