Does anybody have this condition?

I know it is rare, but I have been diagnosed with hyper-mobile joints, and I have checked out the symptoms online.

I think I fit enough of the symptoms to warrant a genetic test, and I know my sister has hyper-mobile joints too.

Is it worth getting tested? Is there any better treatment/understanding? Is there any kind of tailored pain relief or physiotherapy help. Or is the treatment pretty much the same?

Thanks for the advice I hope to receive!
