Small pimples on feet

Our feet bear the weight of our entire body. After walking for a long time, the feet are prone to injury and bacterial infection. Many people have athlete's foot on their feet which is the result of various bacterial infections. Moreover, many people do not care about it at the beginning and just apply medicine when it itches, which leads to intermittent attacks of athlete's foot afterwards. Some people have found that small pimple-like things have grown on their feet after walking for a long time. What is this?

This is a plantar wart.

Plantar warts are common warts that occur on the soles of the feet. It is mostly caused by human papillomavirus infection, which can be transmitted through small breaks in the skin and thus become more and more common. A type of common wart is a growth on the heel, metatarsal heads, or between the metatarsals. In traditional Chinese medical literature, it is called "foot wart" and "Niu Chengjian".

The treatment of this disease generally focuses on external treatment. If there are a large number of rashes, it can be combined with syndrome differentiation and treatment. The main treatment methods are nourishing blood, calming the liver, and promoting blood circulation and unblocking meridians.

Clinical manifestations

1. May feel pain or may not have any symptoms;

2. The skin lesions are round papillary keratin hyperplasia, surrounded by a thickened keratin ring. After removing the surface stratum corneum, there is a loose keratin soft core underneath, and small black spots can be seen formed by the rupture of capillaries and the coagulation of extravasation. If it contains multiple keratinous soft cores, it is called mosaic warts.

3. It often occurs on the heel, metatarsal heads or pressure areas between the metatarsals.
