Corns and calluses are thickened areas of skin that develop after repeated irritation. Usually, they form on your feet because of constant rubbing or applied pressure from improper footwear. If you’ve noticed hardened skin that causes pain and discomfort, then it’s time to schedule an appointment with Dr. Joshi at Advanced Foot Care of NJ, LLC. 

Corns vs. Calluses

People often refer to hardened areas on the bottom of their feet as calluses and the hardened areas on the top of their feet as corns. However, the location of the thickened skin is not what determines if it is a corn or callus. Instead, it is based on the pattern of thickening. For instance, flat and widespread thickening is a callus, and thick and deeper hardened layers are corns. 

Common Causes

As mentioned, repeated skin irritation is usually the cause of corns and calluses. Shoes that are too small or high heels are often the culprits. However, people who have poor circulation or suffer from other foot conditions, such as hammertoes, may also develop corns or calluses. 

Diagnosis and Treatment

As with any foot condition, early diagnosis is important for quality care. Fortunately, corns and calluses are usually slow forming, so patients may notice subtle changes early on. However, it can be difficult for patients to distinguish corns or calluses from a wart. Dr. Joshi has years of experience identifying and treating corns and calluses. As an expert, he can see the difference right away. As part of the examination, the podiatrist may want to do a few x-rays and watch you walk in your shoes to determine the severity of the corn or callus. 

Once a diagnosis is made, then a treatment plan is put into place. For mild corns and calluses, patients may be asked to change their footwear or put padding in their shoes. Dr. Joshi can offer guidance for the best type of footwear for your needs. 

For more severe cases, the podiatrist may shave off a few layers of the thickened skin. This procedure is conducted in-office and is virtually painless because the skin is dead. Cortisone injections may be a solution for patients who experience significant pain. If none of the conservative treatments offer relief, Dr. Joshi may suggest surgery. 


While corns and calluses are incredibly common, some preventative measures could help patients avoid them altogether. Prevention tips include:

  • Avoid wearing ill-fitting shoes for long periods of time

  • Use gel inserts to decrease pressure on your feet

  • Contact your podiatrist right away if you have a foot deformity
