A Morton’s Neuroma (MN) typically causes localised pain between the 2nd/3rd or 3rd/4th toes in the foot and can be sharp in nature. Often it is exacerbated by weight-bearing or narrow footwear and as the neuroma increases in size, there can be slight splaying out of the digits. Often there is no swelling or other superficial changes.
What causes it?
A MN usually arises as a benign swelling of the interdigital nerve (that runs between the toes) and symptoms arises from compression or further irritation of this between the bones of the toes.
How can I help myself?
Think back to when the symptoms came on and what seems to aggravate it. If there is considerable pain, analgesia such as anti-inflammatories can help as can wider fitting shoes.
When to seek help?
If your symptoms are significant and it is affecting your mobility or function, it would be good to have your foot assessed as soon as possible.
What are the treatment options?
Once your clinician assesses you with a thorough history and examination, they may undertake an ultrasound scan to identify if there is a swelling between the metatarsal bones. If there is a MN, your clinician may suggest rehabilitation with a podiatrist, but if symptoms recur then they might advise an ultrasound guided cortisone injection. If this is ineffective, an MRI scan may be undertaken prior to requesting a surgical input.
