There are many clinical conditions that can cause swelling and pain in the legs, such as varicose veins. Varicose veins are a very common clinical condition in which patients experience a sore, painful, and unusual sensation in the legs and localized ulcers. The most obvious symptom is the earthworm-like changes in the blood vessels of the legs, which can even affect normal work in more serious cases. The high prevalence of varicose veins is usually in women, especially in women who often stand for long periods of time, such as etiquette or salesmen, which can lead to the onset of symptoms after long periods of standing. Patients can choose to use elastic stockings for conservative treatment. If the symptoms are not significantly relieved or if the symptoms are more frequent, they can also choose to go to the hospital for further consultation and surgical treatment to relieve and treat the symptoms.
