Reddit reviews A Guide to Living with Hypermobility Syndrome: Bending without Breaking

If you think your problems might be hypermobility-related, perhaps you could explore (if you haven't already):

http://hypermobility.org
(I believe HMS is considered by some experts to be equivalent to one form of EDS)
Their forum has some useful entries on books, papers, and treatments if you browse around.

(For practitioners or keen patients)

I can't guarantee these resources will be applicable to you, but if hypermobility is involved then these are often-cited resources.

I understand that physio exercises working on core and individual joint stability are regarded as very important, in addition to gentle exercise at whatever level you can manage, but ideally led by a physio who is familiar with hypermobility. (It's very easy to cheat on the exercises if you are bendy, which then gives the mistaken impression that they don't help.). Rosemary Keer has some interesting overview papers in this area, which can be found with google.
