try Zeid Abu Mezar he does house visits for physiotherapy for the elderly and those who are ill. from my personal experience hes very professional but I dont know if he does aquatic therapy. He works @Physiomedic but his personal cell is 0785267389
I think your best bet is to go to @Physiomedic they are certified physiotherapists so it actually might be covered by health insurance since it is a legitimate clinic rather than a massage place...and let me tell you the results are excellent and much better than a massage place.
Honestly for medical situations, go to the right people and not just a massage parlor. When I have problems with my neck i go to @Physiomedic they are excellent - ask for Noor she is highly recommended.
