Causes of a Bump on the Bottom of Foot That Hurts to Walk
The foot’s complex structure makes it vulnerable to various injuries and conditions that can lead to painful lumps, including issues with foot ligaments. Dyshidrotic eczema is a skin condition that causes small, deep, fluid-filled blisters on the soles of your feet and the palms of your hands, which can also contribute to foot discomfort. Identifying the root cause of these bumps is key to effective treatment.
The most common foot bumps include:
- plantar warts
- plantar fasciitis
- bursitis
- bone spurs
- neuromas
- cysts or lipomas
- injury or trauma
- tendinitis
When the big toe joint misaligns with the metatarsal bone, it can lead to bunions. Additionally, bursitis occurs when the bursae, fluid-filled sacs that cushion the joints, become inflamed.
Each condition presents unique challenges and requires specific treatment approaches.
Here are the details of these causes.
Plantar Wart
Plantar warts are small growths caused by viral infections, often appearing on areas exposed to friction, such as the bottom of your foot.
These warts develop due to the human papillomavirus (HPV) and are common among people of all ages, with most plantar warts occurring in those who walk barefoot in public places and have cuts or breaks in the skin, which can increase the risk of developing plantar warts. Plantar warts can be painful during walking or running.
Treatment options include over-the-counter remedies, cryotherapy, and laser treatments.
Plantar Fasciitis
Plantar fasciitis occurs when the tissue along the bottom of the foot becomes inflamed, leading to significant foot pain. Common causes include repetitive foot trauma and conditions such as flat feet or high arches. Symptoms often involve a sharp, burning pain that worsens with activity or after long periods of inactivity.
Physical therapy, supportive footwear, and possibly custom orthotics typically alleviate putting excess strain on the plantar fascia.
Bursitis
Bursitis in the foot refers to the inflammation of bursae, small sacs that cushion bones, tendons, and muscles. Bursitis occurs when these fluid-filled sacs become inflamed, particularly due to repeated stress or injury. This condition often results from repetitive foot trauma or wearing tight, ill-fitting shoes. Symptoms include swelling, a visible bony bump, and burning pain that intensifies with movement.
Rest, ice application, and physical therapy are common treatments to reduce pain and inflammation.
Bone Spurs
Bone spurs are bony projections that develop along the edges of bones, often resulting from joint damage. These spurs can cause significant foot pain, particularly on the bottom of the foot, where they may press against soft tissues and nerves, including the heel bone and the metatarsal bone. Risk factors include aging, arthritis, and wearing high heels or poorly fitting shoes.
Physical therapy, steroid injections, or surgical removal in severe cases may be required for treatment.
Neuroma (Morton’s Neuroma)
Morton’s neuroma is a thickening of tissue around a nerve leading to the toes, causing pain and discomfort. Neuromas can also affect the fifth toe. This condition typically affects the area between the third and fourth toes and can result from repetitive foot trauma or wearing tight shoes. Symptoms include sharp, burning pain and a sensation of standing on a pebble.
Corticosteroid injections or surgical removal of the affected nerve are common treatment options.
Cysts or Lipomas
Cysts and lipomas are benign soft tissues surrounding growths that can appear as bumps on the foot. Feet treated for cysts may involve aspiration or surgery. Cysts are typically fluid-filled sacs, while lipomas are composed of fatty tissue. These growths can cause discomfort, especially if they press against nerves or other structures.
Aspiration, corticosteroid injections, or surgical removal are treatment options for persistent or painful cysts.
Injury or Trauma
Injuries such as fractures, sprains, or contusions can lead to the formation of lumps on the foot. It is important to consult an ankle specialist for proper diagnosis and treatment of these injuries. These lumps result from internal and external abrasions and can cause significant foot pain. Calluses can develop from uneven weight distribution while walking. Symptoms of injury-related bumps include swelling, bruising, and tenderness to touch.
Rest, ice application, compression, and physical therapy often promote healing.
Tendinitis
Tendinitis is the inflammation of tendons in the foot, often causing pain and swelling. This condition can affect various tendons, including the Achilles tendon and the posterior tibial tendon. Common causes include repetitive stress, overuse, and improper footwear.
Rest, ice, anti-inflammatory medications, and physical therapy are common approaches to reduce inflammation.

Mobility may be restricted due to pain, making it uncomfortable to walk or stand for extended periods. Limited mobility can also affect the toe joints, leading to further discomfort. A bump can limit the foot’s range of motion, impacting activities such as walking, running, and even standing.
Exercises and physical therapy can enhance mobility and reduce pain, aiding in better condition management.
Visible Growth or Lump
A visible lump could be a fibroma, which is typically soft and movable beneath the skin. People of northern European descent are more likely to develop certain foot lumps due to genetic factors. Not all visible lumps are serious, but they should be assessed to differentiate from more severe conditions.
Determining the nature of the growth is essential for appropriate treatment and symptom management.
Sharp or Throbbing Pain
Sharp pain can suggest a more serious issue, such as a bone spur or neuroma. Sharp pain can also affect the big toe joint, often indicating conditions like bunions, which involve misalignment and inflammation at the joint. Intense, sharp pain may indicate a significant underlying condition that requires prompt medical evaluation.
Identifying sharp versus dull pain can help in seeking the right treatment.
Plantar Calluses: Causes and Symptoms
Plantar calluses form primarily from the friction created by poorly fitting footwear, which leads to a hard protective skin layer. Wearing good quality socks can help prevent calluses by reducing friction and providing better protection. These calluses are thickened skin due to pressure, causing foot pain when walking.
They can feel rough and may interfere with walking due to associated pain.
Treatment Options for Plantar Calluses
If a callus is painful or keeps thickening, it’s advisable to consult a podiatrist for evaluation. Wearing shoes with a pointed toe box can contribute to callus formation by forcing the weight-bearing forward, leading to excessive strain on the toe joints. General treatment recommendations for foot bumps may include proper-fitting shoes and potentially steroid injections or surgery.
Soaking the feet in warm water and using a pumice stone for gentle exfoliation can alleviate mild callus discomfort. Regular moisturizing helps keep the skin soft and prevents calluses from forming.
Prevention of Plantar Calluses
Wearing well-fitting shoes that provide ample space for the toes is crucial in preventing the formation of plantar calluses. Calluses can also form on areas of thin skin, making it important to protect these vulnerable zones. Good foot hygiene, such as daily washing and keeping feet dry, helps prevent issues like calluses. It is important to wear shoes while wearing roomier shoes and wearing shoes that fit properly.
Regular moisturizing can prevent the skin from hardening and forming hardened skin and develop calluses.
Plantar Warts: Identification and Management
Plantar warts are benign growths on the soles of the feet caused by the human papillomavirus (HPV). They are typically rough in texture, highlighting their painful nature, especially when walking or running. Symptoms may include rough surfaces and discoloration, and they can be painful.
Removing plantar warts prevents spreading and reduces discomfort.
Treatment Methods for Plantar Warts
Cryotherapy, salicylic acid, or laser therapy are common treatments for plantar warts. Most plantar warts resolve on their own within two years. Electrocautery, using electric current to burn off warts, can be effective for persistent cases. Immunotherapy is another option, helping the immune system target and eliminate HPV-caused plantar warts.
Consulting with foot care specialists can help determine the best course of action based on the severity and persistence of the warts.
Preventing Plantar Warts
Using bleach to clean surfaces like showers or bathtubs reduces the risk of wart transmission. Walking barefoot in public places like swimming pools and locker rooms increases the risk of contracting plantar warts due to HPV exposure.
Maintaining good foot hygiene, including washing feet daily and keeping them dry, helps reduce the risk of developing plantar warts. Avoiding walking barefoot in public and maintaining good hygiene are critical for preventing plantar warts.
Plantar Fibromas
Plantar fibromas are benign tumors. They consist of fibrous tissue and develop in the arch of the foot. Treating plantar fibromas depends on their size and the presence of symptoms. These growths are usually small, typically less than one inch in size. Painful or rapidly growing lumps in the foot may indicate plantar fibromatosis, which requires medical assessment. Genetics and repetitive foot trauma may contribute to the development of a plantar fibroma. Plantar fibromas can swell, causing painful tightening of the plantar fascia.
Though benign, plantar fibromas’ symptoms should be managed effectively.
Treatment Approaches for Plantar Fibromas
Corticosteroid injections, orthotics, and physical therapy are common treatment options for plantar fibromas. Treatment generally starts with non-invasive methods such as wearing more accommodating footwear, using padding, or applying arch supports. Custom orthotics can be particularly beneficial for larger symptomatic plantar fibromas. Increasing flexibility around the heel and ankle through physical therapy aids in symptom management.
