Intermittent random muscle twitching that jumps around . without weakness is this most likely benign and not als?

Usually benign: Fasciculations does not = ALS. They are more likely a symptom of excess caffeine, lack of sleep, anxiety, stress, etc. Diagnosis for ALS does include fasciculations in the criteria, but only one part of it, and must be accompanied by weakness in the same limb. Twitching as related to ALS indicates dying muscle and therefore weakness which does not come and go. See a Neurologist for eval if needed.
