Chronic alcoholic myopathy develops gradually and is characterized by painless weakness of proximal muscles, atrophy, and gait disturbance. Acute alcoholic myopathy develops suddenly in the context of binge drinking in malnourished chronic alcoholics, and is characterized by painful muscle weakness and myonecrosis. Acute muscle injury is due to the toxic effect of high concentrations of ethanol. Recovery can occur if alcohol is avoided.
