There are several varieties of herniated discs that are possible in the human spine. However, most people tend to use the same term (slipped disc) to refer to the different types of spine injuries. You will hear people referring to a herniated disc as a 'slipped disc,' but these are two distinct terms. A 'slipped disc’ can be a bit misleading because it could mean a lot of things including a bulged disc, prolapsed disc or even a herniated disc. A herniated disc, on the other hand, is a definite scientific description of the real problem associated with it.
