Understanding.
Morton's neuroma is a thickening around an interdigital nerve, often between the third and fourth toes. It can cause a sensation of a pebble under the foot and tingling.
The assessment.
The examination looks for localized pain and differentiates other causes of metatarsalgia. An ultrasound or MRI can supplement the assessment if necessary.
Treatments.
Wide shoes and weight-bearing adjustments are recommended first. An injection may be discussed. In case of persistent discomfort, decompression or nerve resection may be considered.
Follow-up.
After resection, a zone of numbness between the toes is expected. Residual pain or recurrence remains possible.
Decompressing or removing the nerve.
If appropriate footwear, orthotics, and treatments fail, surgery may be performed to release the nerve or remove the affected segment. The choice will be made based on the assessment and your symptoms. Forefoot pain can have several associated causes.
After surgery
Weight-bearing and footwear should follow the team's instructions. Initially, some sensitivity or swelling of the scar may be bothersome. After resection, a period of numbness is expected; persistent pain or a neuroma of the stump remains possible.
Your questions.
Is it a cancerous tumor?+
No. The term "neuroma" here refers to a benign condition affecting the nerve and the surrounding tissues.
Is an image of a neuroma sufficient to warrant surgery?+
No. The location of the pain and the examination must correspond to the imaging.
Should I change my shoes?+
A wider toe box and lower heels can reduce forefoot compression.
