Does ALS cause twitching all over body?
Fasciculations are a common symptom of ALS. These persistent muscle twitches are generally not painful but can interfere with sleep. They are the result of the ongoing disruption of signals from the nerves to the muscles that occurs in ALS.
What do ALS Fasciculations feel like?
Fasciculations may appear randomly or may stay in one muscle for an extended period. The twitch will be most noticeable when the body is at rest. After some time, a person may also experience pain in the affected muscle. The muscle may not respond well to exercise, and many people report feeling weakness as well.
