Swelling and pain in the calves due to varicose veins is a relatively common complication of varicose veins, especially when walking for long periods of time, the swelling and pain in the calf muscles becomes more pronounced, and the swelling and pain is reduced when resting, such as elevating the calf. For the swelling and pain in the calves caused by varicose veins, conservative treatment methods can be used, such as wearing varicose veins elastic stockings when walking or standing for a long time, and reducing the blood stagnation in the veins through graded pressure gradient therapy to slow down the progress of the disease; oral medications such as Mizling and Avalanche can also effectively relieve the swelling and pain of varicose veins in the lower limbs. If conservative treatment is not able to completely reduce the symptoms of swelling and pain in the lower leg, surgical treatment can be performed, and the current minimally invasive surgical treatment will bring greater benefits to the patient and the complication rate is relatively low.
