The most common types of warts that appear on legs are known as flat warts. These warts appear as flat topped bumps that are usually a light brown, yellow or pink colour (see references). The warts will most likely appear in small patches or groups on both of your legs. Rarely will you find a flat wart that is completely isolated. Flat warts also commonly appear on the forehead, on the back of hands and near the mouth (see references). The warts can spread more around shaven areas, especially if you cut one of the warts while shaving. These types of warts can be difficult to treat, and it's important to seek advice from a health professional before applying a strong medication to the warts.
Give the warts time to leave on their own by waiting at least two to three weeks before applying cream or seeking treatment. During this time make sure to carefully shave your legs and avoid cutting the warts.
Use an over-the-counter wart cream if the warts haven't gone away. The cream will help the skin to be saturated in water and then later cause the skin around the wart and the wart to peel off. Continue to step 3 if the warts remain after using the cream.
Consult a doctor to be prescribed a wart medication that contains retinoin, glycolic and salicylic acid (see references). Such medications will help to remove the top layer and then the entire wart. A common prescription to treat the flat warts is Retin-A.
Have cyrotherapy performed if recommended by your doctor. This treatment consists of freezing the wart tissue with liquid nitrogen to kill the tissue so that it can easily be removed.
Have electrocautery performed for extreme cases of flat warts on your legs and if other treatments don't stop your wart problem. This is a laser treatment which can be costly and require multiple treatments to fully remove the warts.
