Formication (pronounced: for-mi-KAY-shun) is a medical term that describes the sensation of insects crawling on or under the skin. The term is derived from the Latin word formica, meaning "ant".

Etymology

The term "Formication" comes from the Latin word formica, which translates to "ant". This term was chosen to describe the sensation because it closely resembles the feeling of small insects, like ants, crawling on or under the skin.

Symptoms

Formication is often described as a tingling, itching, or burning sensation. It can occur anywhere on the body, but is most commonly felt on the arms, legs, and scalp. The sensation can be constant or intermittent, and can vary in intensity from mild to severe.

Causes

Formication can be caused by a variety of conditions, including peripheral neuropathy, menopause, Lyme disease, and drug withdrawal. It can also be a symptom of certain psychiatric disorders, such as schizophrenia and delusional parasitosis.

Treatment

Treatment for formication often involves addressing the underlying cause. For example, if formication is caused by drug withdrawal, then treatment may involve a supervised detox program. If it is a symptom of a psychiatric disorder, then psychotherapy and medication may be recommended. In some cases, topical creams or oral medications may be used to alleviate the uncomfortable sensation.
