I wonder which form(s) are correct amongst the following:

  • "Low back pain"
  • "Lower back pain"

I have read both forms, are they both correct and synonymous?

    BTW-comment, is it right to use "amongst" when referring to two options? I am sure that "among" is incorrect.

    @Cardinal, Franck: Among and amongst also mean exactly the same thing - same as while, whilst, for example (but in both cases the latter form is much less common, particularly in AmE). Sep 1, 2016 at 16:47

    Weird to see that "low back pain" is more common - I would have sworn that in conversation (and TV commercials for painkillers) lower was the more common one.

    "Low back pain" reads like some kind of medical condition, while "Lower back pain" just indicates the location of the pain.

    @FumbleFingers: That's odd; I don't think I've ever heard "low back pain" before. I wonder if there's a dialectal difference? Do British people also refer to that part of the body as the "low back" instead of the "lower back"?

As far as I have gone through this topic online and researched, "low back pain" seems to be the proper medical term corresponding to the issue.

"Lower back pain" is sometimes used in synonymous with that, but in proper medical terms, that doesn't seem to fit in.

Even Wikipedia, WebMD, and Mayoclinic refer to the condition as "low back pain".

Even if I hit Google with the search condition as "lower back" the first response i get is "low back pain" sourced from Appollo Hospitals and others.

As an native english speaker with pain in my back, i commonly use lower back pain as the lower back indicates the area of the back close to the hips or the bottom of the spine. In my interpretation "low back pain" could be read as back pain which is minimal, similar to having "low volume".

EDIT: low should not be used as an adjective for back pain, a better adjective would be minimal.

If the opposite is "upper back", then it should be "lower back". Otherwise the opposite would be "up back", which is obviously incorrect. :D

    Your logic would explain why lower back is used as a synonym of low back.
