Thanks so much. That makes me feel much less worried. :)
I was shocked three different times in my first trimester, each time it was the same as you I felt it from.my fingers to my elbow and once even up to my shoulder, (we had horrible electrical wiring in our old house) and I am 30 weeks and 3 days with a healthy baby boy :) I'm sure you'll be fine, as long as its not a full body shock. Shocking your arm it doesn't affect your abdomen. If you have further worries or issues call your Dr.
