Herniated discs can cause a range of different symptoms, depending on the severity of the injury. Depending on where the herniation occurs and how it affects surrounding nerves, patients may experience anything from mild pain in the affected area to more severe pain radiating through the extremities. Symptoms can also include numbness and tingling in parts of the body related to nerve compression caused by the herniation. Muscle weakness or spasms may also occur due to pressure on the nerve root which can interfere with normal muscle control functions. Finally, some patients with herniated discs have reported changes in bladder or bowel function due to pressure on areas near spinal cord components that affect these activities.
