I have micro twitching/fasciculation of legs, arms, eyes...

Hello, first of all sorry for my English. I am very concerned, for over 5 months I have micro twitching/fasciculation for legs, arms, thighs, feet, are very short at times do not last more than 1-3 sec and I do not even have time to view them.
Also in the eye if I close with such force when you sneeze, or if I close very strong fasciculation occurs which lasts no more than 3 seconds I can see.
Is this normal? It is benign fasciculation syndrome? Dr. Google says fasciculatins can be a symptom of ALS (and I believe a lot of anxiety).
I visited a neurologist, I performed tests of reflexes and balance, and told me to be all anxiety.
I unconcerned? It is normal that happens to me in the eye when closed tightly? Are normal as brief twitching? I have no symptom of weakness in recent months, only I have a lot of muscle tension (anxiety I think reading the symptoms of ALS and remember every day)
thank very much and again sorry for my English.
