I have noticed recently that my right tricep will twitch when doing push-ups. I'm not new to twitches when my muscles are in a relaxed state, however this is the first consistent one I have while using a muscle. Of course after I have scared myself by looking things up, this really has me worried. Anyone else experience this? Is this normal and I am yet again letting my mind get the best of me? I had a clean EMG last month but just like many others I worry about something being missed. My EMG was conducted on both arms and legs but I don't think specifically my tricep.
