Hi
my YD was initially diagnosed with irritable hip when she was 4 and after several bouts of this was diagnosed with juvernile arthritis in her teens. She is now 26 and manages this but I know that at times it gets her down. Fortunately it is not too bad and certainly not as bad as your daughters.

She is now being tested for rhematoid arthritis as it seems to be getting worse. She is reluctant to take too much medication as she doesn't want to get immune to it.

DebBee's advice is excellent as my D does have problems with her weight and I know this exacerbates the problems but it is difficult to exercise when you are in pain. Swimming is excellent for this.

Good luck with your daughter and stay positive, there is so much they can do with medicines these days and developments are always happening.

Any time you want to offload or escape from the issues come on here as there is always someone to talk to.
