I went back for my 2nd emg in 3 months. The first one was clean. Since then I've had fasciculations in my left hand (on the side under my pinkie) and noticed some in my left calf and left foot (side and bottom). At my 2nd neuro appointment I expressed more concern for ALS. My neuro didn't think it could be but agreed to do a 2nd EMG. Of course, only the hand facics happened while in the office. I haven't gotten the official results yet, but she said I have a trapped ulnar nerve. Which makes sense because I lean on my left elbow at the computer all day. She said nerve entrapment could cause facics but she hasnt seen it herself. I wish i could take some comfort in this diagnosis as the cause but it doesn't explain twitching elsewhere (or maybe even the twitching in the hand). Does anyone know if nerve damage from entrapment would show up differently than nerve damage through ALS? I also have brisk reflexes in the knees which scares me. Am I just being paranoid?
