Moderate to large sized disc , when bulge into foramina , make pinch or irritation of spinal heart ( see Figure 1 ) . patient role may be symptomless if bulge is small and does not cause any nip or irritation to spinal nerve . Spinal channel has wide diameter and quad . Large disk jut in to spinal canal may result in pinch or soreness of quada equina ( nerves in spinal channel ) nerves . Large record bulge into spinal canal causes spinal stricture ( see Figure 3 ) . Small or medium sized bulged disc into the spinal canal is often symptomless .
Majority of back pain due to modest disk bulge are self - throttle . Small bulge out discs is often not see in X - ray or MRI as pregnant abnormality . continuing back nuisance make by bulge disc following injury has major impact on work productivity . The decline in work productivity is observed secondary to sick leave , qualify piece of work , and subaltern addition since injury .
