Morton’s Neuroma is a compression injury to the nerve between the toes, which causes enlargement and thickening of the nerve.
This enlargement and thickening of the nerve then takes up more space in-between the bones of the toes, leading to increased compression and more frequent pinching of the nerve.
When the nerve is compressed or pinched a sharp shooting pain, burning or numbness may be felt in the ball of the foot effected.
It commonly affects the nerve that travels between the bones of the third and fourth toes. This area is prone to compression due to the anatomy of the nerve, as it splits at this region to form the plantar digital nerves.
The transverse metatarsal ligament (the band connecting the toes) can also cause compression on the nerves whilst walking.
Nerve impingement is more common in females, due to fashion footwear choices. Due to the ongoing thickening and swelling of the nerve from pressure, if left untreated permanent nerve damage and irritation in the area may occur.
