I've just finished 5 sessions at my local hospital. I suffer with bad hips, knees and shoulders and we mostly worked on my hips and knees. I really liked it. Previously my knees were feeling tight, like they always needed stretching out but after the first session they were better all week and this continued for 3 weeks. The only problem i got was that i'd limp around the supermarket after but it soon wore off.
A few days after my 3rd session, my whole back went into spasm giving me alot of pain and discomfort. My osteopath said this was because my hips and shoulders were out of alignment. I didnt connect this with hydro at the time because i'd found it to be good for me. But the day after the osteopath my left hip and knee gave me alot of pain and I went to hydro the next day as it was much better but then a few days later, again, the same thing happened. I'm waiting for my next lot of pain now
I only connected all this to hydro after reading this topic, seeing some people say it made them worse.
I dont want to put a downer on hydro because i really enjoyed it and i can see how its a good form of physio but for me personally.. i'm not so sure. Maybe i over did things? I never felt exhausted like other people do though..
