This is a thickening of the sheath covering one of the nerves in your foot. Most often, it develops in the ball of the foot between the third and fourth toes. It's also common between the second and third toes.
Why does it happen? Morton's neuroma is caused by repeated pressure or compression between your toes. This irritates and inflames the nerve. The fibers of the nerve sheath become thick with scar tissue. It may be linked to other factors, too. It's linked to problems like flat feet and high arches. It may form because of a bunion, hammertoe or some other toe problem. It can happen if you do activities that put a lot of pressure on the balls of your feet, like running or playing racquet sports. And in women, it may come from wearing high heels or shoes that compress the toes.
What are the symptoms? You may feel sharp, stinging or burning pain when you stand or walk on the affected foot. It may feel like you're standing on a pebble. Your pain may get worse over time. You may also have swelling, tingling and numbness.
How do we treat it? Switching to flat shoes with more room for your toes may help. You may also benefit from orthotics, inserts or pads that take pressure off the area. Medications and injections may relieve pain. If these don't help, we may recommend surgery. Your doctor will create a plan that's right for you.
