Benign Fasciculation Syndrome

Benign fasciculation syndrome is marked by constant tingling, numbness, and twitching in a single muscle or a group of muscles. Though the exact cause of benign fasciculation syndrome is unknown, it is being reported that viral infection, deficiency of magnesium or calcium, and anti-allergic drugs cause it. Anti-inflammatory medications and muscle relaxants help in reducing the symptoms along with lifestyle changes.
