Worried about fasciculations

Dear Ask The Doctor: I have twitchig that dissappears with exercise and possible muscle weakness (Mild). Is this the start of ALS?

Dear Justin: It is not likely that corresponds to ALS, but these symptoms , in a young aged person as yourself, may be due to a stress related situation or anxiety. Sometimes involuntary muscular contractions, called fasciculations can occur as a result of Hypokalemia (low potassium), peripheral nerves or muscular problems, or simply occur in a spontaneous way with no identifiable cause, like the cramps. These fasciculations usually cause a temporary nuisance and typically resolve on their own without treatment. When muscle fasciculations continually recur, it is time to seek an evaluation by a physician. The primary treatment of muscle fasciculations involves methods to relax the affected muscle. This typically involves stretching, massage, and heat application.
