Psych Central   By Renée Grinnell  The false, abnormal feeling
that insects are crawling on or under one’s skin, often
accompanied by stinging or biting sensations. Formication is a
type of tactile hallucination. Its many causes include various
medical conditions, altitude sickness, prescription drug side
effects, and drug withdrawal.  Example: An alcoholic patient
leaps from his bed and dances around the room in a frenzy,
swiping at invisible insects on his arms and shouting, “Get them
off me!”    Subscribe to Our Weekly Newsletter  Find a Therapist
