A herniated lumbar disc will often compress the nerves and cause the following symptoms: first, sensory impairment of the skin. A herniated disc in the fourth and fifth lumbar vertebra will compress the fifth lumbar nerve, which may cause sensory impairment on the outside and front of the lower leg, the inside of the back of the foot, and the bottom of the foot. Secondly, the strength of the muscles innervated by this nerve may be reduced. A herniated disc in the third and fourth lumbar vertebrae may compress the nerve root of the fourth lumbar vertebra and cause a decrease in the strength of the quadriceps muscle. The herniated discs of the lumbar 4 and lumbar 3 and the compression of the sacral nerve root of the lumbar 5 will cause the tendon reflex to weaken or even disappear. If the above symptoms occur, you can relax the lumbar muscles through massage, which can effectively relieve muscle spasm and improve local blood circulation, mainly for patients with mild symptoms and in the recovery period, but if the symptoms are serious, surgery is required.
