"True neuroma" is a medical term used to describe a benign tumor of nerve tissue. The spelling of "neuroma" is derived from the Greek words for nerve (neuron) and tumor (oma). The pronunciation of "neuroma" is /njuːˈrəʊmə/ (noo-ROH-muh) using the International Phonetic Alphabet (IPA). The word "true" is used to distinguish a neoplasm composed of nerve tissue from other types of tumors that can mimic a neuroma. Regular check-ups with a doctor can detect and treat any underlying conditions affecting the nervous system.
A true neuroma, also known as a bennignant neuroma or a neuroma proper, is a pathological condition characterized by the development of a non-cancerous growth or tumor in nerve tissues. Specifically, it refers to the formation of an overgrowth or thickening of nerve fibers, typically occurring in the peripheral nervous system. This condition usually affects sensory nerves, commonly found between the metatarsal heads in the foot or between the toes.
True neuromas are often caused by chronic irritation or compression of the nerve, leading to the formation of scar tissue and an abnormal growth. This can result from repetitive trauma, such as frequent use of ill-fitting shoes or abnormal foot mechanics. The most common type of true neuroma is called Morton's neuroma, which occurs specifically in the intermetatarsal spaces of the foot.
The distinguishing feature of a true neuroma is the presence of a defined, localized, and palpable lump or nodule along the course of the affected nerve. This lump is typically firm and tender to touch. Common symptoms associated with true neuromas include pain, tingling, numbness, or a burning sensation in the affected area. These symptoms are often exacerbated by activities that put pressure on the affected nerve, like walking or wearing tight shoes.
Treatment options for true neuromas vary depending on the severity of symptoms. Conservative measures may include changing footwear, wearing custom orthotics, using metatarsal pads, and physical therapy. If conservative treatments fail to provide relief, more invasive options like corticosteroid injections or surgical removal of the neuroma may be considered.

The term "true neuroma" is used to describe a specific type of benign tumor that arises from nerve tissue. The etymology of the word can be broken down as follows:
1. True: The word "true" comes from the Middle English word "trewe", which is derived from the Old English word "trowe", meaning faithful or trustworthy. It has roots in the Proto-Germanic word "treuwaz", ultimately from the Proto-Indo-European root "deru-", meaning firm or solid.
2. Neuroma: The term "neuroma" is derived from two Greek roots: "neuron", meaning nerve, and "oma", meaning tumor or swelling. "Neuron" originates from the Greek word "neurṓn", related to the Sanskrit word "náras", both meaning sinew or tendon.
