A little more health concerns, less disease concerns
often have outpatients complaining to me: I am afraid of cold on both lower limbs, just like I am put in water all year round. I have seen many other departments such as vascular surgery and no cause was found, and I don’t know what the situation is. I generally recommend that patients have a lumbar MRI to see if there is lumbar disc herniation . Patients usually have lumbar disc herniation after the examination, and the treatment effect is obvious according to lumbar disc herniation. It turns out that fear of cold in the lower limbs is also caused by lumbar disc herniation. Today, let’s learn about the causes of lumbar disc herniation leading to coldness in the lower limbs.
First, let’s understand what lumbar disc herniation is? Lumbar disc herniation refers to the lumbar disc herniation caused by degeneration, trauma or chronic injury, which causes the disc to herniate backwards, compressing the surrounding nerves, thereby producing corresponding symptoms, especially sciatica , and numbness and cold fear in the lower limbs.
What is the reason why lumbar disc herniation causes coldness in the lower limbs? Many people have fear of coldness in their lower limbs. In this case, people often attribute cold hands and feet to the fact that the temperature is too low or the constitution is weak and cold, causing blood circulation to be improper. Little do people know that the root cause of cold legs and feet may not necessarily lie in the weather, but is most likely caused by lumbar disc herniation. Lumbar disc herniation The herniated disc tissue stimulates the sympathetic nerve fibers of the paravertebrae or the sympathetic nerve fibers of the sinus nerve, which reflexively causes blood vessels to contract lower limbs, and patients will feel cold in the affected limbs. This phenomenon is also called cold sciatica. The abnormal sensation in the lower limbs is mainly due to coldness and the temperature of the affected limb is low. This is because the pain of the affected limb reflexively stimulates the sympathetic nerve fibers along the side of the vertebrae, causing sympathetic vasoconstriction.
How should patients treat this condition?
Since the fear of cold in the lower limbs is caused by the stimulation of the sympathetic nerve fibers by the intervertebral disc tissue, improving the stimulation of the sympathetic nerve fibers by the intervertebral disc can generally improve the symptoms. In clinical practice, sympathetic nerve block therapy, sympathetic nerve radiofrequency therapy, or intervertebral foraminis are generally used to improve sympathetic nerve function and promote local blood circulation in the patient, thereby improving the symptoms of cold-feeling with lumbar disc herniation.
Now you know why lumbar disc herniation causes coldness in the lower limbs.
