I too have it and the pain didn't hit till 37 years of age....
It is so frustrating!
My DD was diagnosed today and once again I know more than the Dr.
Hang in there!
Hi! I have a son who is diagnosed with EDS Hypermobility. Sometimes I doubt the diagnosis because he doesn't have the pain associated with the condition. He has several other health problems, which may, or may not be a part of an Ehlers-Danlos "Syndrome" (dysphagia, reflux, orthostatic intolerance, scoliosis, hormone deficiencies, and more).
Perhaps if his orthostatic hypotension wasn't so severe, he would have more pain, because he would be more active, I don't know.
I wanted to direct you to Dr. Forest Tennant, a pain management specialist. I have heard from many EDS'ers who are getting very excited about some of Dr. Tennant's research, which justifies and explains their pain. I don't know much about it, since I am focused on finding answers to other problems right now, not pain, but you may find some answers on Dr. Tennant's website. There is also Dr. Brad Tinkle's "Joint Hypermobility Handbook", available online, which I found extremely helpful in explaining most of the associated co-morbidities, and some of the treatments available.
I hope you are able to find some relief for your pain, and helpful information for you and your parents.
