WHAT ARE THEY?
Veins carry blood back to the heart. Valves inside the veins ensure the blood flows in one direction only. If these valves do not function well, the blood can flow backwards and veins can become enlarged.
There are many different sizes of varicose veins, ranging from small “spider” veins to large, bulky veins. Varicose veins commonly occur in the legs and feet and can be accompanied by leg discomfort. Standing or sitting in one place for a long time can make these symptoms worse. If left untreated varicose veins generally become larger and more numerous over time.
The veins have a tubular structure with a thinner, more supple muscle layer than the arteries. They are equipped with flaps to prevent reverse blood flow, called venous valves. These valves ensure the blood
flows in one direction only, preventing venous reflux.
TYPES OF VEINS
Venous valves become damaged and allow blood back flow and veins can become enlarged, or varicose.
WHAT IS IT LIKE?
If discomfort occurs it can last for a few days to a week. Walking, low impact exercises, and stretching are encouraged starting the day of treatment and help people get better faster. Strenuous activities should be avoided for two weeks, but after that there are no restrictions.
