It's so hard to tell some details with only a xray for information.
If it is fairly obvious on the xray then a follow up with MRI might be the next step, also it would help to rule out other possibles for pain & symptoms.
Have you had any MRI at all yet?
I think with those they are able to do more precise measurements and probably a better image of what might be going on.

But if Insurance or costs are a factor, then I guess it depends on how bad your pain & symptoms are, If it is worth pursuing /pushing for the MRI or not.
