Numbness and coldness caused by poor blood circulation.
Circulation Treatment for Numbness/Coldness

Numbness and coldness are signs that blood circulation is not functioning properly somewhere in the body.
Poor circulation can lead to venous insufficiency and venous pain.

Numbness refers to a loss of sensation or a tingling, prickling pain in a specific area. Coldness is a condition in which the hands or feet feel unusually cold even when the temperature is not low. Both numbness and coldness indicate that normal blood flow is being disrupted within the body. When blood circulation becomes abnormal for various reasons, symptoms such as coldness, numbness, or aching pain in the hands, feet, or legs may occur. These symptoms appear more often in women than in men, especially in women over 40 or after childbirth. Because poor circulation that causes numbness and coldness can result from many different factors, it is important to identify the exact cause and provide the appropriate circulation treatment.

CAUSE OF DISEASE

Cause of Disease

The main cause of numbness and coldness is vascular abnormalities.

The most common cause of poor circulation that leads to numbness and coldness is vascular dysfunction. When the vascular system does not function properly, conditions such as varicose veins, venous insufficiency, and microcirculatory disorders may develop in addition to numbness and coldness. Varicose veins occur when the valves inside the leg veins malfunction, causing blood to flow backward. Since numbness and coldness can also result from venous insufficiency and microcirculatory disorders, it is important to examine the microcirculation carefully during treatment.

  • Varicose veins

  • Venous insufficiency

  • Microcirculatory disorders

FEATURE

Characteristics of Numbness/Coldness

Numbness and coldness are often regarded not as a medical condition but as temporary discomfort that will soon disappear. As a result, many people leave them untreated until the symptoms worsen. The symptoms themselves do not directly cause complications. However, if they result from poor circulation, such as in varicose veins, complications related to that underlying condition may occur. As such, numbness and coldness should be recognized as important warning signs, and prompt examination and appropriate treatment are necessary.

CAUTION

Precautions in Circulation Treatment for Numbness/Coldness

To identify the exact cause, your doctor, a vascular specialist with over 20 years of experience, personally conducts the examination.

For numbness and coldness, a thorough examination is the most important step. These symptoms in the hands and feet can have many different causes, making them difficult to treat without identifying the exact source. Accurate diagnosis through detailed examination is essential for proper treatment. At Sun Vascular Clinic, we perform advanced diagnostic evaluations to determine the precise cause of numbness and coldness. Your doctor, with extensive expertise in vascular care, uses state-of-the-art ultrasound equipment comparable to that of university hospitals to carefully examine the deep veins, superficial veins, perforating veins, and connecting junctions, as well as the microcirculation. If the examination reveals that the numbness or coldness is due to vascular abnormalities, treatment is performed to strengthen the weakened vein walls and restore normal blood flow by correcting venous reflux.

* Symptoms may vary and may appear in a mix of early, mid, and late stages depending on the progression of the disease.

Medication / Injection Treatment
Medication Treatment
This treatment is performed when varicose veins are detected at an early stage. It is used to prevent the progression of varicose veins or to relieve symptoms.
Sclerotherapy
This procedure involves injecting medication into the vein to close off the affected vessel. It is a simple treatment suitable for patients whose symptoms are not severe.
Procedures / Surgeries
VenaSeal
(Horizontal Valve Sealing)
VenaSeal is a treatment that injects medical adhesive into the vein to improve symptoms of varicose veins.
In cases of saphenous vein reflux, the junction between the saphenous vein and the deep vein is sealed horizontally and closely to form an angle near zero degrees, preventing recurrence.
Water Tunnel Laser
This treatment closes the vein using high-energy heat of 500-1000°C generated by the laser. It uses a diffused laser for safety, and the surrounding tissue is protected by a water tunnel that minimizes heat damage. The latest 1940 nm laser achieves an excellent closure rate with less thermal energy compared to older models, providing a safer treatment option.
ClariVein
This method uses a rotating-blade catheter to mechanically stimulate the inner wall of the vein, followed by an injection of a sclerosing agent. There is no heat damage or heat-related side effect.
Mild Radiofrequency Treatment
This procedure closes refluxing veins using heat energy of 100-120°C generated at the tip of a radiofrequency catheter. Like the laser method, it applies the water tunnel technique to maximize safety.
Vein Stripping Surgery
This traditional method is performed under local or general anesthesia. It involves making a small incision in the skin, tying off the refluxing vein, and removing it from the body. It may also be performed in combination with laser treatment.
