What Is a Neuroma?
A neuroma is a thickening of nerve tissue that may develop in various parts of the body. The most common neuroma in the foot is a Morton’s neuroma, which occurs between the third and fourth toes. It is sometimes referred to as an intermetatarsal neuroma. “Intermetatarsal” describes its location in the ball of the foot between the metatarsal bones. Neuromas may also occur in other locations in the foot.
The thickening, or enlargement, of the nerve that defines a neuroma is the result of compression and irritation of the nerve. This compression creates enlargement of the nerve, eventually leading to permanent nerve damage.
Anything that causes compression or irritation of the nerve can lead to the development of a neuroma. One of the most common offenders is wearing shoes that have a tapered toe box, or high-heeled shoes that cause the toes to be forced into the toe box.
People with certain foot deformities – bunions, hammertoes, flatfeet, or more flexible feet – are at higher risk for developing a neuroma. Other potential causes are activities that involve repetitive irritation to the ball of the foot, such as running or court sports. An injury or other type of trauma to the area may also lead to a neuroma.
If you have a Morton’s neuroma, you may have one or more of these symptoms where the nerve damage is occurring:
- Tingling, burning, or numbness
- A feeling that something is inside the ball of the foot
- A feeling that there’s something in the shoe or a sock is bunched up
The progression of a Morton’s neuroma often follows this pattern:
- The symptoms begin gradually. At first they occur only occasionally, when wearing narrow-toed shoes or performing certain aggravating activities.
- The symptoms may go away temporarily by removing the shoe, massaging the foot, or by avoiding aggravating shoes or activities.
- Over time the symptoms progressively worsen and may persist for several days or weeks.
- The symptoms become more intense as the neuroma enlarges and the temporary changes in the nerve become permanent.
To arrive at a diagnosis, the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor attempts to reproduce your symptoms by manipulating your foot. Other tests or imaging studies may be performed.
The best time to see your foot and ankle surgeon is early in the development of symptoms. Early diagnosis of a Morton’s neuroma greatly lessens the need for more invasive treatments and may avoid surgery.
In developing a treatment plan, your foot and ankle surgeon will first determine how long you’ve had the neuroma and evaluate its stage of development. Treatment approaches vary according to the severity of the problem.
For mild to moderate neuromas, treatment options may include:
- Padding. Padding techniques provide support for the metatarsal arch, thereby lessening the pressure on the nerve and decreasing the compression when walking.
- Icing. Placing an icepack on the affected area helps reduce swelling.
- Orthotic devices. Custom orthotic devices provided by your foot and ankle surgeon provide the support needed to reduce pressure and compression on the nerve.
- Activity modifications. Activities that put repetitive pressure on the neuroma should be avoided until the condition improves.
- Shoe modifications. Wear shoes with a wide toe box and avoid narrow-toed shoes or shoes with high heels.
- Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation.
- Injection therapy. Treatment may include injections of cortisone, local anesthetics or other agents.
When Is Surgery Needed?
Surgery may be considered in patients who have not responded adequately to non-surgical treatments. Your foot and ankle surgeon will determine the approach that is best for your condition. The length of the recovery period will vary, depending on the procedure performed.
Regardless of whether you’ve undergone surgical or nonsurgical treatment, your surgeon will recommend long-term measures to help keep your symptoms from returning. These include appropriate footwear and modification of activities to reduce the repetitive pressure on the foot.
UPDATE 3/23/20: In attempt to maintain the safety of our patients, employees, and the community, the office is physically closed, other than for the care of patients with urgent concerns / emergenices only. Attempts will be made to return phone calls Monday through Thursday from 9AM to 1PM. Please use the "Request an Appointment" resource above to request an appointment. If an established patient, we encourage you to log into the Patient Portal and send a message to Dr. Barnes or the office with any questions or concerns. Thank you.
TeleHealth and Tele-Visits in the time of COVID-19
Step Ahead Foot & Ankle Clinic, PC has initiated a TeleHealth Service during the COVID-19 Pandemic for a number of reasons:
1.) Our top priority has always been, and continues to be, Patient, Employee, Community Health and Safety.
2.) With the primary goal of triaging, or prioritizing what's urgent and what's not, Dr. Barnes seeks to help patients with the foot concerns over the phone or computer. Caring for patients in this way, and arranging for visits in clinic if necessary (infections, ulcerations, injuries) and in a controlled environment, she hopes to do her part in allowing to the Urgent Cares and Emergencies Rooms help those with needs related to the virus.
3.) Although Dr. Barnes obviously cannot physicially treat you or other patients over the phone or computer, she can hopefully see if your concern would be best treated physically, and arrange for this to be done. If she can help give you direction and advice over the computer or phone, she will do so. This particularly applies to you if you have foot pain, as many treatment options can be relayed in this way (stretches, shoe recommendations, orthotic recommendations).
4.) During this time of anxiety, stress, and uncertainty, Dr. Barnes wants to do her part in helping you do the things you need to do (caring for a loved one, running outside for stress relief, or walking on a treadmill at home, for example) without foot pain interfering. She does't want you to have to wait months or an indefinite period of time for you to get back on your feet! "CLICK HERE TO REQUEST A TELEVISIT."
