Varicose veins are twisted and dilated veins. Any vein can become varicose; however, the most frequently affected veins are those of the legs and those of the feet. This is because standing and walking with an upright posture increases the pressure in the veins of the lower part of the body.
For many people, varicose veins and spider veins, a frequent mild variation of varicose veins, are simply an aesthetic vein disease in legs. For other people, varicose veins can cause pain and discomfort. Sometimes, varicose veins cause more serious problems.
Varicose veins can also be a sign of an increased risk of other circulatory problems. Treatment may involve personal care measures or medical procedures to close or remove the veins in vein center.
Symptoms of venous insufficiency
Varicose veins may not cause any pain. The signs that you can have for varicose veins and need vein therapy are the following:
- Veins that are purple or dark blue
- Veins that appear twisted and protrude, often, like laces on the legs
When painful signs and symptoms are manifested, they may include the following:
- A feeling of pain or heaviness in the legs
- Burning, pulsation, muscle cramps and swelling in the lower extremities
- Worsening pain after sitting or standing for a long time
- Itching around one or more veins
- Bleeding from varicose veins
- A painful cord in the vein with changes in color to red skin
- Changes in the skin, hardening of the vein, inflammation of the skin or ulcers in the skin near the ankle, which means that you have a severe form of vascular disease that requires medical attention from your vein specialist.
Causes of venous insufficiency
The arteries carry blood from the heart to the rest of the tissues. The veins return the blood from the rest of the body to the heart so that the blood can circulate again. To return blood to the heart, the veins of the legs must work against gravity.
The muscular contractions in the lower legs act like pumps, and the elastic walls of the veins help the blood to return to the heart. The small valves of the veins open as blood flows to the heart and then close to prevent blood from flowing backward.
Complications in venous insufficiency
The complications of varicose veins, although rare, include:
- Ulcers: Extremely painful ulcers can form on the skin near the varicose veins, especially near the ankles. Ulcers are caused by the accumulation of long-term fluid in these tissues, which is caused by the increase in blood pressure in the affected veins.
- Usually, a discolored spotis seen on the skin before an ulcer forms. Check with your vein doctor immediately if you suspect you have an ulcer.
- Blood clots: On some occasions, the deep veins of the legs dilate. In such cases, the affected leg can swell considerably. Any sudden swelling of the leg justifies urgent medical attention to Veins Specialist Doctor, as it may indicate a blood clot, a condition known medically as thrombophlebitis.
Bleeding: Occasionally, leg vein problems that are too close to the skin may explode. Usually, this only causes slight bleeding. However, any bleeding justifies medical attention, since there is a high risk of it happening again.
