Disc problems tend to get worse with age. Aggravation or any injury or any stress can cause a painful disorder known as a slipped disc, herniated disc, pinched nerve, or ruptured disc.

A herniated disc can sometimes be completely painless, but a degenerative disc can cause intense pain. Degenerative means that the condition is likely to get worse over time. Most patients with a degenerative disc will periodically experience continuous tolerable pain followed by increasing intensity of pain that will ...
