If you sometimes feel that you are "walking on a marble," and you have persistent pain in the ball of your foot (forefoot), you may have a condition called Morton's neuroma. A Morton’s neuroma is inflammation on a nerve in your foot. More specifically, it’s an enlargement in the interdigital nerves between the metatarsal bones that connect your foot to your third and fourth toes (your middle toes closest to your pinkie toe).
Also known as an interdigital neuroma, a Morton's neuroma is a benign (non-cancerous) tumor of a nerve. Morton's neuroma is not actually a tumor, but a thickening of the tissue that surrounds the digital nerve leading to the toes. This thickening can lead to various levels of pain or discomfort in the forefoot that may limit your ability to perform certain activities.
These are the most common symptoms:
· Persistent burning or sharp pain in the ball of the foot may radiate (spread out) into the toes, especially during weightbearing activities like running or walking. Night pain is rare.
· Patients frequently describe the sensation of having a pebble or marble under their forefoot as they walk.
· Pain is typically between the base of the third and fourth toes, but it can occur between the second and third toes as well.
· There may be numbness or an unpleasant tingling in the toes.
· Sprinters may feel pain as they push off from the starting block.
If a Morton’s neuroma isn’t treated, it can cause nerve damage or chronic pain in your affected foot. Visit a healthcare provider as
soon as you notice any Morton’s neuroma symptoms.
