What Causes Pain On Bottom Outside Of Foot? And extends up into the ankle and is referred to as lateral foot pain. It is possible for it to happen before, while doing or after activities like walking and running. Pain in the lateral aspect of the Foot can make it difficult for a person to stand or even move around.

A variety of symptoms can be brought on by lateral foot pain, most of which are determined by which part of the Foot is being affected.

The following is a list of the most common symptoms:

  1. Discomfort on the lateral aspect of the ankle
  2. The Foot that is prone to instability
  3. Swelling
  4. Tenderness
  5. A challenging time walking
  6. Susceptibility to ankle sprains
  7. Challenging conditions for standing on one Foot

Where Do Pain Bottom Outside Problems Come From?

lateral foot

Pain outside the ankle and foot is referred to as lateral foot pain.

There is a wide variety of potential causes for lateral foot pain. Most of them result from conditions that did not adequately treat. These might include the following:

  • Inflammation of the ankle joint, as well as scar tissue
  • Arthritis
  • The presence of minute fissures in the bones of the Foot and the ankle
  • Tendon inflammation
  • Nerves that have been stretched, torn, or compressed (especially those passing through the ankle)

Conditions Can Cause Pain In The Lateral Aspect Of The Foot

Ankle Sprain

Ankle Sprain

An ankle sprain is an injury to the Foot's ligaments that does not involve a fracture or dislocation of the bone. Over eighty-five percent of ankle sprains result in lateral foot pain, making this one of the most common reasons for foot discomfort.

Cuboid Syndrome

A cuboid syndrome is characterized by a dislocation of a portion of the cuboid bone, one of the lateral foot bones. This injury could have been avoided if the bone hadn't been subjected to excessive tension or weight.

This syndrome typically manifests itself in individuals who participate in excessive sports and physical activity levels without adequate time for recovery between bouts of exercise. Additionally, the cuboid syndrome may be caused by wearing shoes that are too tight.

The cuboid syndrome is a rare condition that can cause pain in the lateral aspect of the Foot and is frequently misdiagnosed. It can cause symptoms that last for a long time, such as pain, weakness, and tenderness.



Bunions may cause pain in the lateral aspect of the foot.

A bone defect known as a bunion causes the foot's big toe to turn inward and point toward the other toes. As a direct result of this, most of a person's weight is distributed across the lateral aspect of the Foot when they are walking or standing, which can result in discomfort.

Genetic predisposition or poorly fitting shoes that crowd the toes can contribute to bunions' development. In severe cases, surgery may be required to realign the toes and adequately remove the bunion.

Peroneal Tendonitis

The overuse of the tendons in the peroneus muscle can lead to a painful condition known as peroneal tendonitis. These two tendons attach at various points on the lateral side of the Foot and run from the back of the calf, over the lateral edge of the lateral ankle, and down to the back of the Foot.

This condition causes the tendons that attach to the peroneus longus muscle to swell or become inflamed, which leads to pain on the lateral side of the Foot and in the heel.

Peroneal tendonitis can develop in a person's knee if they run excessively or place their Foot in an abnormal position. A sprained ankle can also result in this condition.

Fractures Caused By Stress

Fractures Caused By Stress

Repetitive motions in sports and other forms of exercise can cause a bone in the outer part of the Foot, known as the metatarsals, to crack and break into small pieces. It's possible that the symptoms of this injury won't be too severe at first, but they'll only get worse over time.

Corns And Calluses Both

Corns and calluses tend to form on the outside of the Foot, also known as the lateral side. They frequently appear because the body produces multiple layers of skin to shield the Foot from the damaging effects of friction and repeated stress. Corns, on the other hand, can penetrate deeper into the skin and cause pain, whereas calluses rarely cause discomfort.



When the joint in the Foot is affected by arthritis, the patient will experience pain in the lateral aspect of their Foot. Rheumatoid arthritis is the form of arthritis that affects most people.

Tarsal Coalition

The condition known as tarsal coalition is congenital, which means it is present at the time of birth. When the tarsal bones in the back of the Foot do not connect correctly, a condition known as a tarsal coalition can develop. This peculiar connection between the two bones in the Foot is frequently the cause of discomfort and stiffness in the Foot.

The condition known as tarsal coalition is hugely uncommon. The American Academy of Orthopaedic Surgeons estimates that the disease affects approximately one person out of every one hundred.

What Different Ways Can This Condition Be Treated?

Pain in the side of the Foot can last for a while and usually requires medical attention.

Immediate Relief

Foot pain can often be alleviated by simply taking it easy and propping the Foot up.

A person can get reasonably quick relief from mild lateral foot pain by following the RICE method, which consists of:

Put Down The Foot

  • Applying ice to the Foot for intervals of twenty minutes at a time
  • Applying pressure with an elastic bandage to the Foot
  • Raise the Foot so that it is above the level of the heart.
  • One can choose from a variety of elastic applications that are offered for sale on the internet.



Resting the affected Foot and taking over-the-counter pain relievers and anti-inflammatory drugs are effective treatments for moderate to mild cases of lateral foot pain. A medical professional may recommend anti-inflammatory medication when the symptoms are more severe.

Physiotherapy (Physical)

The next step is physical therapy if the prescribed medications are ineffective. This type of therapy aims to ease tension in the muscles, promote healthy blood flow, and facilitate healthy recovery of the Foot. The physician may also suggest wearing stabilizers to provide additional support and protection for the ankle.

Alternative Medical Procedures

Alternative Medical Procedures

A physician may prescribe steroid medication in the event of injury to the more delicate tissues of the Foot and ankle.

The medical professional might recommend immobilizing the Foot if the bone is injured.

Electric stimulation, laser or light therapy, or even surgery, in sporadic and severe cases, are some other treatments that might use in conjunction with medications.


The doctor will most likely conduct a physical examination of the Foot as part of the diagnostic process for lateral foot pain. The doctor will evaluate the range of motion as well as the stability of the Foot. The physician will also look for areas of swelling, foot deformities or injuries, and signs of pain in the patient's Foot.

The doctor may also suggest diagnostic tests to determine the root cause of the discomfort in the Foot. A magnetic resonance imaging (MRI) scan or an X-ray could be among these.



Most cases of lateral foot pain are due to mild pre-existing conditions, which, if left untreated, can worsen significantly over time. People with the most severe forms of the disease may experience pain whenever they move their Foot or stand upright.

When a nerve is compressed, it can cause pain in the lateral aspect of the Foot, and the individual may experience a loss of some or the sensitivity in their Foot.

Simple preventative steps, such as getting enough rest, can help a person avoid experiencing pain in the lateral aspect of their Foot. Walking, running, jogging, or cycling while wearing shoes that provide arch support for the Foot can also be beneficial.
