KATHMANDU: As we are now in the midst of the cold season, many people are facing various seasonal health issues, including swelling of the hands and feet, allergies, blisters, cracked skin, itching, and more.
Among these, swelling of the hands and feet, medically known as chilblains, is a particularly common problem.
What causes swelling of the hands and feet?
Chilblains are primarily caused by poor blood circulation in the extremities due to the cold.
This condition is more prevalent in children and affects women and thinner individuals more than men or those with a larger build.
Smokers are also more prone to this issue, and for some people, it can be hereditary.
Dr. Isha Poudel, a dermatologist, notes that children have been seeking treatment for chilblains this winter, just as they have in previous years.
While this problem is common in areas with harsher winters, such as the Himalayan region, it also affects residents of Kathmandu during the cold months of Push Magh (mid-December to mid-February).
Children, teenagers, and women who spend a lot of time in cold or wet conditions are especially at risk.
Symptoms of chilblains
The symptoms of chilblains typically appear in the areas most exposed to the cold, especially the hands and feet. Common signs include:
Itching, burning, and swelling of the affected areas.
Redness that may later turn dark blue.
Tingling, prickling, and pain in the fingers and toes.
Blister-like sores filled with fluid.
If untreated, these sores can burst and turn into open wounds.
Treatment for chilblains
In most cases, chilblains can be treated at home by keeping the affected area warm and following proper care.
However, if the condition worsens, it is advisable to consult a doctor. Both oral and topical treatments may be prescribed, including medications to help dilate blood vessels and improve circulation.
In cold weather, blood vessels constrict, which impairs circulation. To counter this, medications that promote blood flow may be necessary.
Additionally, a diet rich in nutrients is essential for maintaining overall body warmth.
How to prevent chilblains
To avoid developing chilblains, the most effective strategy is to minimize exposure to the cold. If you must work in cold conditions, make sure to:
Wear warm gloves and socks to protect your hands and feet.
If you need to work in water, use lukewarm water whenever possible.
When sending children outdoors in the cold, ensure they are dressed warmly with gloves and socks.
For school-going children, always ensure they wear gloves.
It’s also important to avoid rapidly warming your hands and feet in hot air after being in the cold.
Doing so can worsen the swelling and pain. Instead, try massaging your hands and feet gently, as this can stimulate blood flow.
Soaking your hands and feet in warm water and applying a nourishing lotion can also help alleviate symptoms.
When to seek medical attention
If you experience significant difficulty in performing daily tasks, or if you have severe itching, pain, or swelling, it’s best to consult a doctor.
For mild symptoms such as minor itching or burning, keeping the affected areas warm is often sufficient, and the condition should gradually improve on its own.
