Morton’s Neuroma – physio advice

If you’ve ever suffered from pain or tingling between the base of the toes – then it could be something known as Morton’s Neuroma.

It commonly happens between the 3rd and 4th toe but it could equally happen between any of them. The cause is an inflamed and thickened nerve and it’s something that’s often seen in middle-aged women but also runners of all genders and ages.

Wrong shoes?

One potential cause (and the reason it could affect women more than men) is the impact of wearing tight and/or high-heeled shoes. However the cause could be biomechanical and that’s what we’re going to focus on in this blog.

The cause of this is often down to excessive or uncontrolled pronation – something you might have come across in running shops where they talk about how your foot lands when you run.

Pronation is essentially the foot rolling in during walking or running, not  a problem or an issue in itself. The problem is down to how it’s controlled.

There are a few key stages involved in controlling this pronation

    1. When our foot lands, stabiliser muscles on the outside of the hip contract. These then quickly let go and the knee starts to move inwards
    2. The control then becomes the role of the calf muscles, and particularly the muscles behind the shin, which we have discussed previously in another blog. These muscles run underneath the foot and one in particular, tibialis posterior, starts to let the foot flatten as it relaxes
    3. The weight is then on the inside of the foot and we push off with the big toe, or certainly more along that side of the foot

When the muscles are tired or simply not strong enough, instead of controlling this rolling movement it just collapses inwards as shown in this video. This can lead to any number of things including hip issues, knee pain, shin splints, bunions or Morton’s neuroma.

For Morton’s neuroma the the lack of muscle control means the bones in the foot, in particular the metatarsals, can get squeezed together which then pinches the nerves between them. Over time, this can lead to the thickened and painful nerves typical of the condition,

There does also seem to be an increased likelihood of getting a Morton’s neuroma if the foot is turned out excessively, particularly if you do a lot of walking/running as it can exacerbate the squeezing together of the metatarsals.

How is it assessed?

It’s a fairly straightforward problem to assess, with key signs including the symptoms mentioned above along with an area that’s tender to touch. Squeezing the metatarsal together with your hand will also reproduce the pain

How is Morton’s Neuroma treated?

It’s important to identify how the problem has occurred – so this involves looking at your running/walking technique (or gait) along with some functional tests such as a single leg squat.

Subject to these assessments, we can prescribe an exercise programme and, in the long-term, this will be the most important part of the treatment.

Commonly used exercises for this are these single leg heel raises on the edge of a step and this single leg squat whilst holding weights. These both help to strengthen the muscles in the area as well as further up the lower limb chain, particularly the single leg squats.

For quicker pain relief we usually recommend joint mobilisations along with a deep massage to the bottom of the foot. After this and with the exercises mentioned above, it’s possible to see a noticeable improvement in just a few weeks.

In some cases surgery is required, whereby part of the nerve is removed. This animation shows the basics of what happens in the surgery. Rehab following will again focus on the biomechanical reasons why the problem occurred in the first place.

The bad news is that it can take several months to get rid of the problem completely, whether treated conservatively or with the help of surgical intervention,  therefore any long walks or training plans should be assessed with your physiotherapist.

  1. Hi Sue,

    That should be fine. General rule of thumb is that discomfort is ok during the exercise as long as it’s not really flaring the problem up either at the time or over the next couple of days. Would be worth getting it treated, initially trying some conservative treatment. If you’d like to discuss any options just give us a call or email and we’d gladly talk through the best options – just go to the contact page on this website

  2. I am having success in pain mgt. with cbd oil. I have a simple pedaling machine to arrive soon for home use. I cannot afford hefty gym memberships. Would light pedaling do anything positive to changed the physiology of my morton’s? Thanks.

    1. Hi Pat,

      Morton’s neuroma can often be a result of biomechanical issues, specifically the strength and timing of each of the muscles through the leg as you walk/run etc. In simple terms, the light pedalling is unlikely to cause any detrimental effect on your symptoms, although it would be pleasantly surprising if it improved or resolved them. The key would normally be addressing any biomechanical or strength issues, which are often fairly simple to identify but could be from a number of places including the hip or muscles in the lower leg.
