According to Dr. Vu, when the patient has all the above symptoms, it is very likely that he is suffering from venous valve failure of the lower extremities.

Regarding the cause of this condition, Dr. Vu said, when blood from the heart is pumped to feed the organs in the body, the blood going to any part of the body will provide energy for that place, and at the same time bring nutrients to the body. It is excreted through the capillaries and travels from the veins to the heart to the lungs to filter and exchange oxygen. These cycles rotate continuously. “When the blood from the legs wants to go to the heart, it will be like climbing upstream, the blood climbs small steps. If the venous valve fails, it will open and every time the muscle brings blood up, a little will drop back down. The blood drops down causing stagnation in the lower part, increasing the pressure in the vessel. At this time, the blood will seep out and cause the legs to swell. Besides, the metabolites in the blood stagnate in the muscles, causing the muscles to contract, aching and painful. uncomfortable feeling,” explained Dr. Vu.

Venous valve failure usually has 2 cases. The first case is a very large dilated blood vessel, visible to the naked eye through the zigzag blood lines, this dilated state does not have internal blood stasis, so it is only related to cosmetic problems. The second case is internal valve failure, fluid seeps into the muscle, a lot of waste stagnates and a painful contraction occurs in the muscle.

For people who do jobs that have to sit or stand constantly like teachers and office workers, they should occasionally stand up, sit down, and exercise. Raise your shins up, don’t slouch straight down. At night, you should put your feet on a high pillow for better blood flow to the heart.

Some other methods to limit numbness and other night cramps, such as exercises on tiptoe, heel stretch strengthen the leg muscles.

If the measures are not effective, the doctor will consider giving the patient medication to stabilize the blood vessel walls. In some severe cases, if there is a lot of leg edema, sometimes diuretics must be used to remove excess fluid in the body.

In addition, some cases need surgery such as: large tortuous blood vessels, severe valve failure that does not respond to medical or conventional treatment.

“One method we often hear about is wearing venous stockings in the legs, the stockings will hug from the toes to the thighs to limit the space, limit blood stasis. Although effective, but when worn, the stockings are very effective. It’s quite difficult due to the tight grip and wrap, so the patient needs to choose the right type for the leg,” – Dr. Vu encouraged.
