Ehlers-Danlos syndrome & HMS support + discussion

So today the physician assistant at the rheumatologist told me I'm hypermobile and my chronic pain is in large part from overextended muscles and tendons because of my joints being hypermobile. Which, okay, that probably explains why I can't stretch without hitting owwww before actually hitting stretch? Also, maybe fibromyalgia, here go get blood work.

Consequently I'm looking at this Prevention.com article with some suspicion. "Start by positioning yourself until you feel a slight stretch in the muscle, then hold the stretch for a full minute for the most benefit." Yeah no the point of this exercise is to reduce my pain levels, thanks...

Does anyone have good resources on this sort of thing? Because I'm supposed to get into a low-impact exercise routine. But I know perfectly well that if it hurts worse, I won't.
