What's wrong with the red spots on my feet?

Many people have the problem of red spots on their feet. This problem may be caused by eczema, allergies, or of course, a disease such as vascular nevus. No matter what disease causes it, you need to go to the hospital for treatment in time to prevent the condition from further deteriorating. Below, we will introduce to you the common causes of red spots on the feet!

1. Eczema

Eczema is a skin inflammatory reaction with severe itching caused by a variety of internal and external factors. It is divided into three stages: acute, subacute and chronic. The acute phase has an exudative tendency, while the chronic phase has infiltration and hypertrophy. Some patients directly present with chronic eczema. The skin lesions are characterized by polymorphism, symmetry, itching and easy recurrence.

The causes of eczema are complex and are often the result of the interaction of internal and external factors. Internal factors such as chronic digestive system diseases, mental stress, insomnia, excessive fatigue, mood changes, endocrine disorders, infections, metabolic disorders, etc., and external factors such as living environment, climate change, food, etc. can all affect the occurrence of eczema. External stimuli such as sunlight, cold, dryness, heat, hot water washing, various animal furs, plants, cosmetics, soaps, artificial fibers, etc. can all induce it. It is a delayed allergic reaction caused by complex internal and external factors.

2. Allergies

Under normal circumstances, when foreign substances enter the human body, they generally face two fates. If they are recognized by the body as useful or harmless substances, these substances will coexist harmoniously with the human body and will eventually be absorbed, utilized or naturally excreted. If these substances are identified as harmful, the body's immune system will respond immediately to expel or eliminate them. This is the protective role of the immune response. Immune response is one of the important functions of the human defense system, but if this response exceeds the normal range, that is, when the immune system attacks harmless substances, this situation is called an allergic reaction. Allergy is a disease, because unprovoked attacks can also damage normal body tissues, and the immune system can even attack and destroy the body's own tissues at times, which is very harmful to human health.

3. Vascular nevus

Vascular nevus is the most common benign tumor in infants and is formed by the proliferation of vascular network during the embryonic period. There are two types of vascular nevi: hemangiomas and vascular malformations. Vascular malformations are vascular malformations that may persist throughout life. Hemangioma is caused by the proliferation of vascular endothelial cells. Strawberry hemangioma and cavernous hemangioma are more common clinically. Hemangiomas should be treated actively, and laser therapy, hormone therapy, radiotherapy, cryosurgery and surgery can be selected as appropriate.
