Our family just started the Methyl B12 shots as well. Someone had mentioned numbing cream for my dd whom had anxiety over having an injection. The needle is incredibly small and she had to ask if it was over! Not a big deal for her on the second go around. We put a small amount of the numbing cream (from a compounding pharmacy, prescription needed) on a bandaid, then wait 20 minutes.
My ds has recently had a major exacerbation, including new tics and OCD. Unfortunately, we added several new things to his routine, B12, 5MTHF, and Prednisone. So, we are unable to decipher what caused the behavioral changes that came on so suddenly. I was going to post to see if others have had reactions to the B12 shot or Prednisone...heck he might just be getting sick.
I too am interested in others feedback, as you put "it the good, the bad and the ugly"
