4 months ago I started developing pins and needles sensation all over my body. Had bloods taken and my b12 level was 84. I then had 5 injections within 2 weeks and I started having serve symptoms like muscle spasms and extreme tingling. My symptoms seemed to calm down (but never went away). Now my symptoms have become severe again but my blood tests came back normal.
Anyone else had anything similar and does it take a while for symptoms to go?
