Common Causes of Bumps on the Bottom of Foot That Hurt

A lump or painful bump on bottom of foot can be due to various causes such as infection, trauma or tumor. Some people also have a hard spot on bottom of foot that is painless. These bumps may remain the same size or grow slowly or rapidly. If you have a painful spot on bottom of foot, find out what causes it and what remedies can help reduce your symptoms.

Painful Bumps on Bottom of Foot

Most foot lumps are harmless, but talk to your doctor about a persistent painful bump on bottom of foot. It is important to find out if you have a serious problem or not. Below are the most common causes and treatment for them. 

1.   Corns and Calluses

A corn or a callus is the most common cause, which results from constant pressure or friction from your tight shoes. Repeated trauma can also cause a hard spot on bottom of foot. Calluses can be really painful especially if you often stand on your feet all day. These may be associated with some redness and swelling, which usually get better with rest.

Treatments: Using moleskin pads can also help relieve pain from a corn. The doctor can recommend using medicated patches, trimming calluses and corns, or correcting them with surgery.

2.   Plantar Warts

A plantar wart is a hard spot on bottom of foot, usually appearing on the heel/ball of the foot, where the most pressure occurs. Excessive pressure also may cause your plantar wart to grow beneath a callus.

Warts are caused by viruses (human papillomavirus or HPV), which enter your body through small breaks,cuts, or weak spots on the skin. They may go away without any treatment. However, if the warts cause a painful bump on bottom of foot and spreads, you can treat them with home remedies or over-the-counter medications. Repeated treatments may be necessary because they tend to recur.

Treatments to remove warts include:

If these home remedies do not work, talk to your doctor about other treatments such as:

3.   Plantar Fibromas

Another possible cause of painful spot on bottom of foot is a plantar fibroma, which is usually found in the arch of the foot, embedded in the band of tissue called plantar fascia. This non-malignant growth can develop in one or both of your feet, and usually persists without treatment. It is not known what causes this condition.

Pain on bottom of foot may be felt when standing or walking barefoot or even when wearing shoes. However, some people do not experience pain.

Treatment options include:

4.   Foot Blisters

Another cause of painful bump on bottom of foot which look like bubbles or bumps are blisters that result from friction. This causes the outer skin layers to rub against each other, separate, then get filled up with fluid. It usually happens when you wear new shoes or poorly fitting shoes.

Foot blisters must not be ignored because they can develop bacterial infection, which can lead to impetigo (a localized infection) or cellulitis (a widespread skin infection). Diabetic individuals are more likely to develop foot blisters, which can become seriously infected.

Treatment options include:

If you are an athlete or just trying to exercise and have recurrent blisters that do not improve with these simple measures, consult a specialist who can perform a gait analysis on you. Your blisters may be due to some problem with your anatomical gait, which is causing the excessive friction on your skin.
