Hi everyone, just wanted to how other people feel prior to their injection. My injection was due in 6 days time, but for the last few days was feeling sick, pains in my stomach. Last time I went to bed really early feeling unwell. This morning woke up feeling very sick, really weak and my muscles were aching all over. I struggled to work this morning. After about an hour I was still feeling sick, I was in the classroom my hand started going all like pins and needles, I started feeling dizzy and felt like i was going to pass out, to which I took myself out of class very quickly. I had to lye down for over half an hour feeling very weak. I managed to ring my G P to get an emergency app to which I was then given my b12 injection. My nurse told me to book an appointment to check where my b12 levels were and also to check my iron. Which I was tested both 8 moths ago. She said that my levels might be low and may need a loading dose. How do people feel when their injection is needed?
