Morton's neuroma
Morton's Neuroma
Morton's Neuroma (pronounced: MOR-tunz nuh-ROH-muh), also known as Interdigital Neuroma or Morton's Metatarsalgia, is a benign (non-cancerous) growth of nerve tissue that develops in the foot, usually between the third and fourth toes. It is named after Thomas George Morton, the American surgeon who first described it in 1876.
Etymology
The term "neuroma" comes from the Greek words "neuron" meaning "nerve" and "-oma" meaning "tumor". Despite its name, Morton's Neuroma is not actually a true tumor, but rather a thickening of the tissue that surrounds the digital nerve leading to the toes.
Symptoms
Symptoms of Morton's Neuroma can include:
- Pain in the ball of the foot
- Numbness in the toes
- A feeling as if you're standing on a pebble in your shoe or a fold in your sock
Causes
The exact cause of Morton's Neuroma is unknown, but it may occur as a result of irritation, pressure or injury to one of the nerves that lead to the toes. Factors that may contribute to Morton's Neuroma include:
- High-heeled shoes, especially those over two inches tall
- High-impact athletic activities such as jogging or running
- Certain foot deformities, such as bunions, hammer toes, flatfeet or more flexible feet
Treatment
Treatment for Morton's Neuroma usually involves conservative therapies, such as changing footwear, using arch supports or foot pads, and taking over-the-counter pain medications. In some cases, your doctor may recommend injection therapies or surgery.
