Need advice on getting tested for Elhers Danlos Syndrome

My rheumy was the one that told me I had EDS, but it came several years after my AS diagnosis.

You’ve been to a rheumatologist right ? If your rheumatologist is solid they should be able to suss it out . Ask lots of questions and be your own advocate . I’ve had autoimmune disease for 17 years and I’ve always pressed for information and testing .

I've never heard of that.
