So far, there is no simpler examination and diagnosis method other than CT and MRI examination, but mastering the following characteristics of medical history can do some simple self-prediction of lumbar disc herniation, and at the same time can provide sufficient and reliable clues to physicians during consultation. (1) Low back pain with unilateral lower limb radiating pain, which is one of the typical symptoms of lumbar disc herniation. Most cases usually have low back pain first and then low back pain with radiating lower extremity pain later; some actions that increase abdominal pressure can aggravate the symptoms, such as straining to defecate, sneezing, or even coughing; in patients with low back pain first, the pain can last for a few days or up to several years. The areas are mostly in the lower low back and lumbosacral region. This type of pain has deeper sensory sites, a slower process, and a limited or widespread dull pain in the low back that is inaccurately localized, aggravated by activity, and relieved by bed rest. (2) Numbness is also a condition that can be felt subjectively by the patient. If not taken seriously, it will slowly develop into a “woody” sensation; mostly in the lateral and posterior calf, heel and outer edge of the foot; (3) weakness, the patient may feel inflexible toe movement. (3) Weakness, the patient may feel inflexible toe movement. This may be manifested as reduced upward power of the big toe; it may also be manifested as reduced upward or downward tensing power of the dorsum of the foot; (4) Low temperature of the lower extremity, which occurs less frequently. (4) Low temperature of the lower extremities, which is less common. One leg may feel “cold”; the lower leg, foot and toes are the most obvious; sometimes there may be unilateral or bilateral edema of the lower extremities. If these conditions occur in your life, it is likely that you have a lumbar disc herniation, and you should go to the hospital in time.
