"Why Are There Purple Capillaries on the Calf?"

1. Varicose veins of the lower extremities: Varicose veins of the lower extremities may be caused by congenital weakness of the superficial venous wall or incompetent valve closure. After developing the condition, patients may experience venous protrusion and tortuosity, leading to purple capillaries on the calf, along with symptoms such as heavy limbs and hyperpigmentation. Under a doctor's guidance, patients can take medications such as Diosmin Tablets and Maizhiling Tablets, which can increase venous tension and control the progression of the disease.

2. Capillary dilatation: Capillary dilatation may be caused by genetics, prolonged high fever, or exposure to radiation. This condition causes the skin's capillaries to dilate persistently, leading to purple capillaries on the calf. Following the doctor's advice, laser therapy and photon therapy can be used to remove dilated capillaries and aid in patient recovery. Patients should avoid standing or sitting for long periods and refrain from crossing their legs frequently.
