Hi mankyscotslass - sorry about the rather abrupt post earlier ... I had to dash out to a hospital appointment!
My sister has had problems with hypermobile joints since very early on ... and now spends much of her time in a wheelchair, as she dislocates very easily.
As a child, it was just thought that she was clumsy - and, with her having the hyermobile form of eds, it meant that she bruised rather easily - which led to my sister and I being on the "at risk" register for a while, as SS and HCPs didn't accept that she bruised incredibly easily.
She has problems with writing - her fingers dislocate when she writes for too long - and has never been able to do gymnastics or play ball sports, as there's too much possibility of her dislocating.
It wasn't until she was 16 that EDS was diagnosed with her - and by that time, she'd already had about 10 different lots of surgery to try to tighten various joints.
Having seen the problems it can cause, I'd recommend you try and get a referral to a rheumatologist - as EDS is a collagen disorder, and the rheumatologists seem to be the people who deal with it most.
The most emminent doc is Prof Bird some of his work here who is based up in Leeds - my sister was under treatment with him for a while, and has since handed over care to the rheumatologists in South Wales where we live.
Good luck. I'd also get dd to steer clear of the gymnastics - my sister has had fairly good results in terms of reducing dislocations when she has done exercise to tone and strengthen the muscles surrounding the worst affected joints... swimming is always a good one!
