Aqua Therapy Success for disc/back pain and injuries?

[Amazon]

Has anyone had success with hydrotherapy for disc problems? I have run the gamet of physical therapy, pain medication, antiInflammatories, muscle relaxers, and a facet injection. I was looking for feedback on hydrotherapy and how/if it helped.

My mother has been doing hydro therapy for a couple years now ( she has sever injurys) and finds it extreamly helpful so long as she does it properly and listens to her physio if she goes off track or over does it she has little to no help and hurts again but while she keeps it up it is VERY helpful as an example when going well she can walk around the shop for about a hour but when going bad she can't barely walk to her wheelchair
