Hi I've had this for a while almost a year. Basically my upper abdominal area pulsates or twitches at the same time as my pulse when I put my fingers on my neck to see my pulse rate. What could this be? Also I have twitches in my legs and arms however these are random and don't last for too long. Is this a concern for something like Als. I read that als fasciculation will be constant, which is what my abdominal is like. Not the other areas. Please any help will be great. I don't smoke but I do drink coffee I stopped for a long time and noticed that it didn't make a difference. Also I take magnesium zinc and potassium to see if it helps. No luck. Had a blood test few months ago and all levels were fine (liver kidney blood vitamins minerals thyroid etc) Thanks.
