What's wrong with my feet turning black and purple?

Black feet may be caused by poor blood circulation in the soles of the feet. We can promote blood circulation in the soles of the feet by massaging the soles of the feet and soaking the feet. In addition to poor blood circulation, other possible causes of black and purple soles include vascular inflammation or paronychia caused by malnutrition. Let's learn about the causes of this disease.

Factors that lead to vasculitis include:

Malnutrition can lead to vasculitis, which can cause the patient's feet to turn black and purple. Studies have shown that a lack of vitamin B and vitamin C in the human body can lead to vascular diseases, of which vasculitis is a common one. The clinical use of large doses of vitamin C can promote wound recovery. However, other information shows that if too much fat is consumed and excessive cholesterol is consumed, the resistance of blood vessels will be reduced, and vasculitis may also be caused.

Cold and damp blood vessels can cause vasculitis. Relevant experiments have shown that cold and damp can cause obvious contraction and spasm of the patient's blood vessels, and the duration will be slightly longer than that of normal people. This shows that the limbs of vasculitis patients are sensitive to cold.

Smoking has a great relationship with the onset of vasculitis. According to surveys, a very large proportion of vasculitis patients have a history of smoking. Tobacco contains nicotine, which can cause spasms of small blood vessels in the human body and cause vascular damage, which may lead to the onset of vasculitis.

Why do feet turn black and purple? Bacterial infection can cause vasculitis. Diseases such as paronychia and tinea pedis are closely related to the occurrence of vasculitis. This may be due to infection factors that reduce local vascular resistance. It is also believed that bacteria and certain fungi are likely to be the source of antigens that form the complex, and that bacteria and their degradation products continuously enter the body from the pharynx, lungs, intestines, and skin. Therefore, antibodies against a variety of bacteria can often be found in human serum. Since these antibodies are present in small quantities, the complexes formed can be cleared from the blood or other tissues without damage. If soluble antigens enter the blood and combine with antibodies to form complexes, which are deposited in blood vessels, they will cause vascular diseases, vasculitis being one of them.

Patients must choose the treatment method that suits them according to their condition. In addition, they must develop good living habits in daily life, which will also help the treatment.
