The twitching pain in the leg muscles of the elderly more than a year after the spinal cord cervical spondylosis surgery is generally not related to the surgery, and the possible causes include catching a cold, lack of calcium, and nerve damage. 1. Cold: If you don’t pay attention to keep warm, it will cause your legs to get cold, which will cause muscle spasms and twitching pain in your legs, which is a normal phenomenon. 2. Calcium deficiency: because of lack of activity after fracture, partiality, insufficient sun exposure, resulting in insufficient intake and absorption of calcium ions, the body lacks calcium, muscle nerve excitability increases, which can cause leg muscle twitching pain. 3. Nerve injury: If spinal cord cervical spondylosis is combined with nerve root injury, due to the long recovery time after nerve injury, the nerve injury will not be recovered immediately after the surgery to relieve the compression, and twitching pain in the leg muscles may still occur one year after the surgery. The causes of twitching pain in the leg muscles one year after surgery for spinal cord cervical spondylosis in the elderly are more varied, and may also be related to Parkinson’s syndrome, cerebral infarction and other diseases. If the symptoms continue to be unrelieved, it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment.
