Formications, also known as formication, is a medical term used to describe a sensation that feels like ants crawling on or under the skin. The word is derived from the Latin "formica," meaning ant. This peculiar and unsettling sensation is often described as prickling, tingling, itching, or creeping, similar to the sensations experienced when ants crawl on the body. However, no actual ants or insects are present, and the sensation is perceived entirely in the absence of any external stimuli.
Formications can be caused by various physiological or psychological factors. Physical causes include nerve disorders, such as peripheral neuropathy, multiple sclerosis, or certain vitamin deficiencies. Mental health conditions, such as anxiety disorders, substance withdrawal, or hallucinogen use, can also trigger formication. Additionally, certain medications, such as antipsychotics or stimulants, may induce this sensation as a side effect.
The sensation of formications can range from mild and temporary to severe and chronic, depending on the underlying cause. While formications themselves are not considered a medical condition, they are often a symptom or a manifestation of an underlying issue. Thus, it is crucial to address the root cause of formications in order to alleviate or resolve the sensation.
In summary, formications refer to the abnormal feeling of ants crawling on or underneath the skin, without any actual insects present. This sensation can be caused by various physical or psychological factors and is perceived as tingling, prickling, itching, or crawling.
