Bump on side of foot near arch
If you develop a bump on your foot, near your big toe, it’s a logical assumption to think you’re developing a bunion. Even if you think that you know what’s causing your foot problem, you should make an appointment with your trusted podiatrist. There are several other foot conditions that can cause lumps to form on your foot.

What exactly is a bunion?

A bunion is a lump of bony tissue on the outside of the joint between your big toe and the rest of your foot. It’s caused by the misalignment of your toe and the metatarsal bone in your foot.

The bump causes excess friction on the side of your foot, leading to calluses and corns. It can also cause foot pain, especially when you walk and put pressure on the misaligned bones, tendons, and muscles.

There are a variety of treatments available for bunions, depending on the severity of your foot problem. Mild bunions often resolve with a change of footwear, orthotics, and physical therapy to gently realign your toe. In more severe cases, you may need surgery to realign your bones or to remove an excess bony tissue that has formed on your joint.

5 Foot problems that resemble bunions

Arthritis

Arthritis of your big toe joint causes swelling that can look similar to a bunion on the side of your foot and also cause foot pain when you walk or put pressure on your foot. A foot problem called hallux rigidus develops, causing bone spurs to develop on the joint. This deformity leads to irritation and inflammation of the skin, which makes the bump look even more bunion-like. Arthritis is often treated with anti-inflammatory medication and the application of ice.

Ganglion Cyst

A ganglion cyst is a cyst or non-cancerous tumor that forms on a joint. While these cysts are more common on your hands or wrists, they can also develop on your feet and ankles. Ganglion cysts are linked to joint trauma and often cause pain when you move the affected joint. Ganglion cysts are often softer to the touch than a bunion. You should not try to pop or remove a cyst on your own. Make an appointment for diagnosis and professional medical treatment.

Gout

Gout is a specific form of arthritis that develops when high levels of uric acid cause crystals to develop in your joints. Gout commonly affects the feet and toes. It causes your toe to become swollen and red, which leads to it being mistaken for a bunion. Gout causes a significant amount of pain and decreased mobility. Gout is typically treated with medication to reduce the inflammation and pain while also clearing the extra uric acid from your system.

Bursitis

When your bursa, the sacs of lubricating fluid in your joints, become irritated and inflamed, you develop a condition called bursitis. It causes swelling, redness, and pain in the affected joint and can lead to decreased mobility. Bursitis is typically caused by repetitive use or an injury. The condition is painful and can lead to calcium deposits forming in the joint, which amplifies the pain. Bursitis is often treated with rest, ice, and anti-inflammatory medication.

Misalignment elsewhere in the foot or ankle

Misalignment anywhere in your body can lead to radiant pain. For example, if your ankle is misaligned, all the small muscles and tendons in your foot will be affected, which could pull the other bones out of correct alignment. This can lead to inflammation and pain in your toes, the arch of your foot, and up through your legs, knees, and hips. Alignment issues are easily treated with HyProCure®, the minimally invasive placement of a small titanium stent in the natural space between the ankle bone and heel bone to keep the foot properly aligned.

"I've got this lump on my foot—what could it be?" As a foot and ankle surgeon, I am asked this question quite frequently. I always explain that because bumps on feet can signal both serious and non-serious conditions, it is always best to have all lumps and bumps properly examined by a foot and ankle surgeon.   

Bumps on feet can vary in size, from that of a pea to the size of a golf ball. They can also vary in location, from the arch of the foot to the ankle area or elsewhere. They may or may not hurt or cause changes in daily activity. But a lump found in the foot has a possibility of being cancerous, and for this reason, must not be ignored.

The most common type of lump found in the foot is a soft-tissue mass called a ganglionic cyst. This soft, fluid-filled sac is a benign (noncancerous) bump found on the tendons and joints. A ganglionic cyst can be caused by a leaking of jelly-like fluid from the "capsule" surrounding a joint or tendon and may be located on the top of the foot, near an ankle joint or even on the side of the foot. The cyst will not go away on its own and tends to return, even after being drained. The best way to keep a ganglionic cyst from recurring is to have it surgically removed by a foot and ankle surgeon.

Another common type of lump found in feet are plantar fibromas. These often painless, benign masses are fibrous, hard nodules found within the ligament of the foot and are especially common in the arch area on the bottom of the foot. These bumps tend to be less than an inch in diameter but can get larger over time. Nonsurgical treatments, such as steroid injections, physical therapy or orthotic devices, may help relieve any discomfort but will not make the fibroma disappear. Surgery to remove the mass is an option for patients who continue to experience pain following nonsurgical approaches.

For foot bumps that are suspected of being cancerous, we perform a biopsy on the area. A tissue sample from the biopsy is then sent to a lab, and advanced imaging or an MRI may be used to gauge more information about the mass. If it is indeed cancer, the foot and ankle surgeon will perform surgery to remove the mass in tandem with an oncologist for cancer treatment.

Remember, foot bumps do not tend to go away on their own. The sooner we are able to properly evaluate the bump, the sooner a patient can have peace of mind and move forward with treatment, whether surgical or nonsurgical, so they may resume everyday activity.

What does a lump on the side of your foot mean?

Lump On Side Of Foot Summary A lump on the side of the foot near your toes is most likely due to bunions, foot gout or corns/calluses. A lump on the outside of the foot may be caused by peroneal tendonitis, jones fracture or cuboid syndrome.

What is the lump on the outer side of my foot?

Bursitis. This painful condition develops when bursae, the small fluid-filled sacs in your feet, become inflamed. It's typically caused by repetitive stress, such as certain physical exercises or wearing ill-fitting shoes. Bursitis can develop on the sides of your feet, as well as on your heels or big toes.

What is bony bump on side of foot?

A bunion is a bony bump that forms along the side of the foot. A tailor's bunion occurs when this bump is on the outside of the foot, at the base of the little toe. Tailor's bunions are also called bunionettes and are less common than regular bunions.

What does a plantar fibroma look like?

The characteristic sign of a plantar fibroma is a noticeable lump in the arch that feels firm to the touch. This mass can remain the same size or get larger over time or additional fibromas may develop. People who have a plantar fibroma may or may not have pain.
