What might cause foot corns and how it can be treated in allopathy?

Hammertoe: Hammertoes are caused by an imbalance in the muscle tendons that cause the toes to move up and down. One tendon pulls the toe up while the other tendon deforms the toe by pulling it down at the joints in the toe. Your podiatrist can establish by radiographs and by examinaion what specifically causes your hammertoe problem. Surgical intervention may be indicated if the condition is painful.

Corns: Corns can be formed from several different reasons. Most common is from friction or increase pressure points. Make sure to evaluate your shoes. Old shoes need to be replaced. I recommend seeing a podiatrist who can help with different treatment options including prescription ointments to custom orthotics. Don't let them go to long without care, they can lead to ulcers.
