Lumbar protrusion does not usually cause calf swelling.
Lumbar herniation refers to a series of neurological symptoms, such as lumbar pain, radiating pain in the lower limbs, numbness, and limitation of movement, that occur when a lumbar disc protrudes posteriorly or laterally, compresses the dural sac, and irritates the spinal cord or nerve roots. Herniated lumbar discs generally do not lead to compression of blood vessels in the legs and do not affect the vascular system, so they generally do not cause calf swelling.
Calf swelling is generally due to various causes of poor blood circulation in the lower limbs or trauma and inflammation caused by localized swelling, which is commonly caused by varicose veins of the lower limbs, lower limb venous thrombosis, venous valve closure insufficiency, localized infections, fasciitis and other causes.
Patients with swollen calves should go to the hospital in time, and give targeted treatment after clarifying the cause.
