Hi guys I need some help here. I got B12 last night it was painful shot bc of the stupid nurse I told her push it slowly but the dumb ass didn't once she pin it she pushed very fast it was painful. Any way after that I went home and and since then I have tingling in my legs and I feel weakness in my legs! I got little shaking last night. Now I have weakness in my legs along with tingling, why? I got these symptoms before 8 months when I was super angry I got bad cramp in my lower back and my legs along with the weakness in my legs. What's going on n my body? And is that a sign for something bad? Pls help
Thanks
