What is the condition of a hidden toenail called?

The condition of a hidden toenail is commonly referred to as an "ingrown toenail." This occurs when the edges or corners of the toenail grow into the surrounding skin, leading to pain, swelling, and sometimes infection. It commonly affects the big toe and can be caused by improper nail trimming, tight footwear, or genetic factors. Treatment may involve proper nail care, soaking the foot, or, in severe cases, surgical intervention.
