A long, thin red area may be seen as the inflammation follows a superficial vein. This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen. The area may begin to throb or burn. Symptoms may be worse when the leg is lowered, especially when first getting out of bed in the morning. A low-grade fever may occur.
The middle image shows where varicose veins might appear in a leg. Comparison of healthy and varicose veins. Varicose veins are more common in women than in men and are linked with heredity. [16] Other related factors are pregnancy, obesity, menopause, aging, prolonged standing, leg injury and abdominal straining. Varicose veins are unlikely to ...
Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries. Fibrotic tissue may predispose the tissue to ulceration. Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis. In advanced lipodermatosclerosis the proximal leg swells from chronic venous ...
Symptoms classically affect a leg and typically develop over hours or days, [20] though they can develop suddenly or over a matter of weeks. [21] The legs are primarily affected, with 4–10% of DVT occurring in the arms. [11] Despite the signs and symptoms being highly variable, [5] the typical symptoms are pain, swelling, and redness.
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [2]: 826–7 [3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the vein.
If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles.
Superficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis , which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness .
