Round circles of thickened skin on your toes or the sole of your foot could be corns.
Your body forms corns to prevent blistering on your feet, and they’re usually not painful right away.
Hammer toe, bunions, or poor-fitting shoes may be the cause of corns. Over time, corns may become irritated and should be treated.
OTC treatments like corn plasters may help relieve pressure on a corn and allow it to heal, or in some cases your doctor may recommend surgery to remove it.
