I needed to go to the physio often until they worked out what was wrong and what to do about it - then I used my own judgement to decide how much I really needed.

When it got to the stage where most of my appointments were just check ups and I was just doing exercises they gave me to do at home alone I had fewer appointments.

For me it was really expensive the first few months and then eased off. Hopefully you can do the same perhaps?
