A burning sensation in the legs below the knee is a common symptom, especially characteristic of women over 40 years of age. A natural phenomenon is burning and pain in the leg below the knee, caused by overwork, prolonged walking or standing, wearing uncomfortable shoes. In this case, the uncomfortable sensations are removed after rest. But if the burning sensation often bothers, arising even at night, at rest, this is a sign of pathology.
The main causes of burning in the legs below the knee
Let's list the most likely causes of burning, itching and pain in the legs below the knee:
- Thrombophlebitis is a pathology associated with inflammation of the vein wall and the formation of a thrombus in its lumen. This may be due to infection, trauma, changes in blood composition and other factors. The affected limb in this case swells, the skin often turns red, the body temperature rises.
- Varicose veins - with this disease, lengthening and widening of the superficial veins, a change in their shape is observed. Its main causes are heredity, hormonal changes, overweight, etc. The burning sensation due to varicose veins is more pronounced in the evening, accompanied by a feeling of heaviness in the legs, edema, and convulsions may occur.
- Atherosclerosis of the vessels - in this case there is a narrowing of the lumen of the vessels, associated with the deposition of atherosclerotic plaques in them, causing a worsening of the blood supply to the limb. In addition to the burning sensation, patients can feel chill in the feet, numbness of the fingers, blanching of the skin of the legs.
- Obliterating endarteritis is an inflammatory lesion of the arteries of the lower extremities, characterized by their gradual narrowing. The most likely cause of pathology is autoimmune processes. Initial manifestations of endarteritis - burning in calves, "crawling flies", fast fatigue of the legs.
