Hi, I'm Marcos, 29 y/o, turning 30 next march, 8. In setember 2012 everything started to me. I had a Emg in November/2012 and it was clean. I've been twiching all over, just a single pops that lasts less than a few seconds. But since December, in the Christmas, i'm having a persistent twich in my right shoulder. Sometimes it goes for some hours than stop. After two or three days, it come back and yesterday was going on all day. I'm very scarry and i'm thinking to come back to doctor, I don't know. I fear for my healthy since I was a child, but this it's too much for me. I have a little girl and my wife is pregnant again. I just want to cry but I resist, because I don't want to worry her. I do workouts at the gym without any problems, but i'm too scarry with this. Do you guys think should I came back to doc? Please, let me know what u really think. Sorry for my english. God bless you all! Marcos
