A slipped disc sounds like something sliding out of place. The medical wording is more specific.
What is a slipped disc?
OrthoInfo (AAOS) ties the two names together. It says: Another common type of disk injury is a "slipped" or herniated disk .
So the plain-language term and the medical term describe the same injury.
How does it happen?
The same publisher describes the process. It says: If the pressure continues, the jelly-like center may push all the way through disk's outer ring (rupture) or cause the ring to bulge (slip).
Look at what the wording describes: pressure that continues, not a single moment or a single cause.
Next steps
If you suspect a slipped disc, the useful move is an evaluation, and the useful question for a Little Falls reader is what that evaluation costs. Ask any office for its visit fee and agreement terms before you commit.
For general reading, WebMD's pain management center gives a broad view. OrthoInfo's sciatica page covers leg pain that can go with disc problems.
A practitioner's note
Two names for one injury can make a page feel like it covers two things. It covers one, and the decision that follows is about how you will be evaluated and what that commits you to.
