Hydro Therapy

I have been undergoing physical therapy for past 2.5 years, since my injury. Around 6 months ago, I met a guy with Gullian-Barre Syndrome at my previous rehab. He was coming to physical therapy in the morning and again used to go to hydro therapy in the evening.  He said that he had significant improvement in hydro therapy and also asked me to give it a shot. My parents are keen to take me to hydro therapy sessions.

Here in Hyderabad,India, we have only few hydro therapy centers and that are all belonged to same parent hospital group. And each session there is super costly.

When I ask my therapist if he advocates hydro therapy to me, then he would say "Hey, do you want to try it, then lets do it. I have a friend who has a swimming pool. Lets go there for few sessions if you want. Lets get into pool and we can have some exercises."

 He has no experience in hydro therapy. I asked the same question to my previous physio, who moved to other city. She also never had experience with hydro therapy. She just said "You may try if you want. There is no harm in doing it."

I am sure, even if I join hydro therapy sessions, physios there would not have any prior experience with SCIs.

Now, the option I have is to ask my therapist to take me to normal swimming pool and try there. I know it will be weird and may also turn out to be awkward situation but I am ready to take it if it benefits me.

My point is, does it all worth it? Did any of you try hydro therapy? How was the experience? Did you find any improvement because of it? Any inputs about it?

My present condition: My right half of the body has recovered significantly and is "almost normal". In the left half, obliges are responding little. Hip flexors and knee flexors are weak. Knee extensors and Ankle have high spasticity. There is little to good movement in all muscles other than Ankle. So, I can take few steps(ranging from 4-40) based on various factors.

Any help/advice/suggestion from someone who had undergone hydro therapy or has idea about it?
