Don't be afraid of it. I had two SFEMGs on my arms and legs, and then a third on the face. I found the one on the face hurt less than the arms and legs ones. Also, the one on my face was conclusive, whereas the first two (arms and legs) were borderline. I thought this was weird, because I was having a lot of trouble with muscles in my arms and legs, but no trouble with muscles around the eyes. Maybe the face SFEMG is easier to read or something.
