The feeling of leg distension may be clinically caused by the occlusion of lower limb blood vessels, such as venous thrombosis, which can be further diagnosed by color ultrasound of the lower limb. This part of patients are mostly seen in the middle-aged people after 40 years of age in clinical practice, and the proportion of men and women is equal. In addition to the clinical manifestation of leg distension, it is cooler to touch the lower limbs with hands, which is caused by the blood clots leading to poor blood circulation. In addition, nerve compression caused by lumbar disc herniation will also lead to lower limb pain. This kind of patients will generally have the accompanying symptoms of lumbar pain, which is very common in clinical practice, and can be further diagnosed by doing CT of lumbar disc. Varices and other diseases can also cause lower limb pain.
