Recurrence after minimally invasive lumbar disc herniation may present with symptoms such as limb numbness, limb coldness, lower skin temperature of the affected limb, and muscle paralysis. 1. Numbness of the limbs: mainly the proprioceptive and tactile fibers in the spinal nerve roots are stimulated, resulting in numbness of the limbs, the scope and location of which depends on the number of nerve root sequences involved, usually accompanied by pain symptoms in addition to numbness. 2. Cold sensation in the limbs: patients may have cold and chilly limbs due to the stimulation of sympathetic nerve fibers in the spinal canal. 3. Lower skin temperature of the affected limb: because of the pain in the affected limb, the sympathetic nerve fibers next to the vertebrae are provoked, or the sympathetic vasoconstriction is caused reflexively, which triggers sciatica and lower skin temperature of the calf and toes, especially the toes part of the foot is more obvious. 4. Muscle paralysis: because of the root damage caused by the innervated muscle paralysis symptoms of varying degrees, mild muscle weakness, the muscle will lose function. It is recommended that patients exercise more after recovery from surgery, do not overwork, and do not sit or stand for a long time. If recurrence of symptoms occurs, you should go to the hospital to receive timely examination and treatment.
