In many cases, herniation at the C6 level causes no symptoms other than bulging, says the Herniated Disk Authority. Pain and neurological problems only occur when nerves are compressed.
Disk C6 is located in the lower part of the neck and is the cervical region most commonly affected by herniation, says the Herniated Disk Authority. This is due to the weight of the head, frequent movement in the area and the delicateness of the disk itself. It is also common for this region to experience degeneration in disks and a loss of spine curvature. Most often, C6 herniation presents with a painless bulge. However, if a nerve is affected directly, pain and neurological problems can result. Also, it is possible for a herniation at this level to put pressure or strain on the spinal cord, causing pain and necessitating medical care or observation.
Commonly, herniation in the C6 regions is wrongly blamed for pain in the shoulders, neck, upper back and arms, notes the Herniated Disk Authority. However, these problems are more commonly caused by poor circulation to nerves in the affected region. If pain persists after receiving treatment for a C6 herniation, a spinal neurology specialist can help to determine the cause.
