I started to feel my some places are burning or so hot for 2 days. Also I feeling numbness/tingling mixed on my some places too like my left arm's small place, my pinkie finger and like that. I'm using cyanocobalamin for my B12 deficiency but I forgot my injection that I had to have done 3 days ago. Is it about anxiety or B12 deficiency or am I having a stroke or something? (My B12 was 223 1 month ago. My doctor gave me 1000 mcg of cyanocobalamin per week. I used it for 3 weeks, I forgot the 4th one.)
