A bulge in the crook of the leg may be caused by varicose veins, or by popliteal cysts or lipomas.
1. Varicose veins: increased pressure on the veins of the lower limbs or venous insufficiency may lead to varicose veins. The patient’s venous valves may be impaired, resulting in excessive collection of blood in the lower limbs, leading to swelling and the formation of localized lumps.
2. Popliteal cysts: Meniscus injury or degeneration of articular cartilage can lead to popliteal cysts, mainly due to the increase in joint pressure, resulting in the accumulation of joint fluid to the popliteal fossa and the formation of cysts. In the early stage, there may be no obvious symptoms, but in serious cases, joint stiffness, lumps, pain and other discomforts may occur.
3. Lipoma: If the family has the corresponding genetic history, the patient has a certain chance to be affected by heredity, resulting in the appearance of lipoma and the appearance of bulging at the bend of the leg. Lipoma grows slowly, usually without obvious discomfort, but there will be more obvious lumps, which can be treated by surgery.
A bulging lump in the crook of the leg may also be caused by other reasons, it is recommended to consult a doctor in time to clarify the cause of the disease and then targeted treatment.
