We all know the same story: you have pain but all of the tests come back normal and you’re left with no answers.
A recent study dove into the definable differences between hEDS and non-hEDS patients in small fiber neuropathy. Spoiler alter: there were many significant findings!

Slide 1:
Light gray background with dark teal text and orange accent elements. Large headline reads “When Pain Is Real but Tests Come Back Normal: New Research Sheds Light on the Nervous System in hEDS.” Below is explanatory text about hypermobile Ehlers-Danlos syndrome and a skin biopsy study. EDS Awareness logo in bottom right, “Swipe to learn” button at bottom left.
Slide 2:
Orange background with dark teal text. Headline “What is Small Fiber Neuropathy?” followed by two paragraphs explaining SFN causes burning pain, abnormal sensations, and autonomic dysfunction. Includes note that SFN appears in many hEDS patients but hasn’t been systematically compared to standalone SFN. Handle and next page arrow at bottom.
Slide 3:
Dark teal background with white text. Headline “How the Study Was Done.” Shows two orange rounded boxes: “35 hEDS/SFN patients” and “38 iSFN patients” with a play button icon. Describes comprehensive battery of assessments including questionnaires, sensory testing, autonomic testing, and skin biopsy for nerve fiber density comparison.
Slide 4:
Orange background with dark teal text. Headline “What They Found” with three sections: symptom onset earlier in hEDS/SFN group (age 19 vs 35), longer disease duration, and pain more widespread in hEDS/SFN group, noting 34% reported perineal pain versus none in iSFN group, attributed to nerve displacement from tissue laxity.
Slide 5:
Orange background with dark teal text. Continuation of “What They Found” covering autonomic symptoms significantly more severe in hEDS/SFN (POTS in 51.5% vs none), greater loss of autonomic nerve fibers, and unusual alternating pattern of fiber loss and regrowth in hEDS/SFN patients.
Slide 6:
Dark teal background with orange and white text. “Key Takeaways” section with four main bullet points: earlier symptom onset in hEDS/SFN, more severe autonomic symptoms including POTS, greater nerve fiber loss revealed by skin biopsy, and that small fiber involvement appears core to hEDS rather than secondary.
