What are the causes of "old rot leg"? Old rot leg is a disease that mainly affects the mid to lower part of the leg, also known as venous ulcer. It generally appears as a complication of diseases like phlebitis and varicose veins. Once it occurs, it indicates that your primary disease, such as varicose veins, has progressed to its late stage. At this point, while treating the primary disease like varicose veins, you should also pay attention to this complication, old rot leg. So, what are the causes of old rot leg?
The causes of old rot leg have the following characteristics:
The disease commonly referred to as "old rot leg" in folk terms is mainly chronic skin ulcers on the mid to lower part of the calf. In the early stages of the disease, there may only be inflammatory exudation, followed by the development of ulcers that do not heal easily, becoming larger and deeper over time, ultimately leading to complete damage of the skin layers. The surrounding skin around the ulcer is affected, showing atrophy, turning black, causing eczema, with frequent shedding of scales and itching sensations. On the front of the mid to lower part of the calf, the subcutaneous tissue is close to the bone. Once an ulcer occurs, the bone becomes exposed, leading to surface infections and forming chronic osteomyelitis. Some patients suffer for years or even decades without recovery, enduring immense torment.
Humans walk upright, and for blood flow in the lower limb veins to return upward, it must overcome significant gravitational forces. The main secret behind this lies in the pressure difference between arteries and veins. Arterial pressure is high, while venous pressure is low, naturally guiding the blood flow from high to low pressure areas. Additionally, there is the squeezing effect caused by muscle contractions during lower limb activities, along with the venous valves located inside the veins. Some people are born with weak vein walls, or fewer and structurally poor venous valves, leading to reduced functionality. If they stand still for long periods, reducing lower limb muscle activity and insufficient muscle compression, this can obstruct the return flow of blood in the lower limb veins, causing increased venous pressure.
Over time, superficial veins in the lower limbs become dilated and thickened. As the condition progresses, they twist into clusters resembling a bunch of earthworms beneath the skin. Patients often feel heaviness and fatigue in their legs, with some experiencing swelling in the dorsum of the foot or ankle joint. If left untreated, the skin on the lower part of the calf and around the ankle will undergo atrophy, thinning, becoming shiny, with sparse hair, darkening and turning black, developing eczema, and eventually leading to ulcers. A notable characteristic of these ulcers is their difficulty in healing, hence being referred to as "old rot leg."
