If you have looked at the checklist and match the criteria (which based on your description it does sound like you do), this is the current way hEDS is diagnosed so it would suggest you have it. However, a doctor is best to make a formal diagnosis and could help you rule out other types of EDS. I personally got my hEDS diagnosis from a geneticist, but others may be willing to do the job for you. A diagnosis may feel validating, and personally for me it has really helped me get the help I need for my joints. But it is just a label, so do with that what you will!
