Great new study showing that most people have disc bulges and degeneration as a normal part of ageing. Degenerative changes on imaging (MRI’s and CT Scans) are really common. The are not sufficient to cause pain.
An example from Brinjikiji et al 2014: They reviewed all available imaging studies and found that in pain free 50 year olds, 60% had lumbar disc bulges. That’s nearly 2/3 of healthy 50 year olds that have ropey discs. I was taught that was terrible news as a chiropractor. Its not.

From the Conclusion
Imaging evidence of degenerative spine disease is common in asymptomatic individuals and increases with age. These findings suggest that many imaging-based degenerative features may be part of normal aging and unassociated with low back pain, especially when incidentally seen. These imaging findings must be interpreted in the context of the patient’s clinical condition.

Another study highlighted by Meakins, see graph below, says over 80% of pain free 50 years olds have neck disc bulges.
