How long it takes to recover from herniated disc dural sac compression is related to the degree of compression and the specific length of time and the specific type of disease. Slight herniated disc dural sac compression and a relatively short period of time, generally about 2 weeks can be recovered; if the degree of compression is heavier, it takes about 3 months to recover, if the degree of compression is heavy and longer, resulting in irreversible damage to the dural sac or even can not be recovered. Herniated disc dural sac compression, usually caused by disc herniation, trauma, tumor occupation, infection and other causes. Dural sac compression caused by minor disc herniation etc. usually recovers in 2 weeks, but minor dural sac compression caused by infection and tumor lesion needs to wait for the lesion to be cleared before gradual recovery, which depends on the specific time of the lesion clearance, and it may take 2~3 months after the operation. If the dural sac of a herniated disc is more severely compressed, surgery is usually needed, and recovery after surgery takes about 3 months, but if the compression is longer and more severe, causing irreversible damage to the dural sac and nerves or even impossible to recover. Herniated disc dural sac compression need to go to the hospital in time to diagnose and treat the cause of the disease, early treatment, in order to promote the recovery of the dural sac and nerve function.
