Looking for advice on physical therapy

Yes. I did personally, from personal experience if you have pts who listen and care about you, it does work and help. Just don’t forget to do the “homework” they assign you. Those exercises will help you when you aren’t in PT.

Doing it now after back surgery

i am currently doing pool therapy and home exercises.

Water physical therapy helped with mine

I did therapy around 2 and and half years ago. It helped me quite a bit, but if I don't keep up with the at home exercises then I'm hurting.

It's been over 5 years ago, but I did for a few weeks. There was no improvement for me. That's not to say it won't help you.
