A leg that always feels uncomfortable is more likely to be considered a venous system disorder, especially varicose veins. The patient may also have restricted or increased venous blood flow in the lower extremities after activity, and the patient may experience swelling of the extremity, positive acupressure marks, and significant soreness and swelling. Ultrasound suggests obvious varicose veins and slow blood flow in the lower extremities, which can be assisted by wearing compression stockings during activity, and not overexerting and weight bearing during normal times, but should be properly exercised with physical function. For severe varicose veins, surgery is an option if necessary. This is because patients with a long history of the disease may have a combination of local thrombophlebitis and even ulcer formation. The surgery is relatively simple and involves stripping the superficial tortuous, dilated, non-functional vessels under epidural anesthesia, requiring high ligation and postoperative attention to prevent infection and regular medication changes and stitch removal.
