A wart on the foot is commonly known as a common wart on the bottom of the foot, also known as a plantar wart, and can be treated with topical medication, laser or freezing. However, most of the topical medications are corrosive and similar to lasers, they can cause localized trauma to the skin and may affect the patient’s ability to walk or live or work. The most common clinical application is freezing, because the advantage is that it is inexpensive and the local skin is not broken, but the disadvantage is that some patients may have some large local blisters after treatment, and most of these blisters do not require special treatment. In addition, for larger wart, it may be difficult to cure the wart at one time and often requires multiple treatments. After regular treatment, most wart can be cured within half a month to a few months.
