Cervical disc herniations and Fibromyalgia - Cervical disc herniations is the problem found at the cervical disc spine that connect the skull to the back spine. Take a good look at the picture you can count 7 cervical discs at the neck. My local simply call cervical discs as pillow bones as they wrap or support neck bones. If these discs move down or disorder can cause much pain that radiating down the arm. Because of the presence of spinal cord, severe disc herniations can cause spinal cord dysfunction which include weakness in the legs and balance problems. My problem is the herniations of CD5 and CD6 on the left side.
