Atherosclerosis of the lower extremities may cause a drop in skin temperature, intermittent claudication and limb pain. 1. Decrease in skin temperature: When arteries of the lower limbs are sclerotic, the blood supply to the lower limbs will be impaired, and the blood may not be able to reach the endings of the limbs, which may lead to a decrease in the skin temperature, and there will be the performance of cold feet. 2. Intermittent claudication: after arteriosclerosis of the lower limbs, the patients may have insufficient blood supply to the lower limbs in the process of walking, and may have abnormal symptoms such as numbness, stiffness, etc., so that claudication occurs, and it can gradually improve after resting, and can continue to walk. 3. Limb pain: due to poor blood supply, it is likely to lead to ischemia and hypoxia of the muscles of the lower limbs, with the aggravation of the condition, the patient will also have lower limb pain. The above are some typical symptoms of lower extremity atherosclerosis, and must be combined with lower extremity arterial ultrasound, limb Doppler and other tests, which are used to make a clear diagnosis and assess the condition, and can follow the doctor’s instructions to take drugs to improve microcirculation such as Diosmin, and also can be localized arterial balloon dilatation treatment, which can make the condition improved.
