June is “chronic pain awareness month,” so I am featuring Ehlers-Danlos Syndrome Awareness, because last May, EDS official awareness month, was already a busy time for many NEI conditions. EDS can occur in some fibromyalgia, chronic fatigue syndrome and myofascial pain syndrome patients, even though it is a rare condition.
Ehlers-Danlos Syndromes (EDS), pronounced ey-lerz dan-los, are genetically passed from parents to offspring. It is characterized by joint hypermobility, skin extensibility and tissue fragility due abnormal genes that produce atypical proteins that result in imperfection of collagen, which is the protein glue for our tissue.
There are now thought to be six types of EDS. 1) The Classical Type, 2) The Hypermobility Type , 3) The Vascular Type , 4) The Arthrochalasia, 5)The Dermatosparaxis, and 6) The Tenascin-X Deficient.
Symptoms may vary depending upon the type, but there are general symptoms.
Other criteria may include:
The Classical Type of EDS The Classical Type of EDS is characterized by highly elastic, soft, and doughy skin; unusual scarring; and loose joints. This type of Ehlers-Danlos Syndrome combines the types formerly called I and II. Ehlers-Danlos Syndrome, Classical Type is a subtype of Ehlers-Danlos Syndrome.
Hypermobility Type of EDS is characterized by loose joints and chronic joint pain. This form of Ehlers-Danlos Syndrome was formerly called type III. Ehlers-Danlos Syndrome, Hypermobility Type is a subtype of Ehlers-Danlos Syndrome….
The Vascular Type of EDS is characterized by possible arterial or organ rupture as a result of spontaneous rupture of vessels or organs due to the result of even minor trauma. The Vascular Type of EDS is the most serious form of Ehlers-Danlos Syndrome….
Arthrochalasia Type of EDS is caused by mutations leading to deficient processing of the amino-terminal end of proa1(I) [type A] or proa2(I)[type B] chains of collagen type I. It is inherited in an autosomal dominant manner. A skin biopsy can also diagnose this type of EDS
Dermatosparaxis Type of EDS is characterized by severe skin fragility and substantial bruising. Wound healing is not impaired and the scars are not atrophic. The skin texture is soft and doughy. Sagging, redundant skin is evident. The redundancy of facial skin results in an appearance resembling cutis laxa. Large hernias(umbilical, inguinal) may also be seen. The number of patients reported with this type of EDS is small.
Dermatosparaxis Type of EDS is caused by a deficiency of procollagenI N-terminal peptidase. It is inherited in a autosomal recessive manner. A skin biopsy can diagnose this type of EDS.
Tenascin-X Deficient Type of EDS is characterized by joint hypermobility, hyperelastic skin, and fragile tissue. Lacking multiple shrinking (atrophied) scars in the skin that is often seen in the Classic Type of Ehlers-Danlos Syndrome.
If you suspect you may have or have been diagnosed with EDS, there is a plethora of information at the Ehlers-Danlos Syndrome Network.

As discussed in Integrative Therapies for Fibromyalgia, Chronic Fatigue Syndrome, and Myofascial Pain: The Mind Body Connection, some of the symptoms of Ehlers-Danlos Syndrome overlap with FM and CFID, however the diagnostic criteria is different, therefore it can be considered a mimicking or co-existing condition. Joint hypermobility and skin disorders have been more frequently observed in children with CFID than in otherwise healthy children, (Baron, et, al, 2002), and some types of EDS can perpetuate the development of myofascial pain syndrome.
Stretching is often indicated for FM and CFID with comorbid MPS, however, if EDS is also present one much use great care, because overstretching already lax tendons can increase the likelihood of joint subluxation (the appendage coming out of its functional socket.). EDS patients with MPS need guarded specific local stretching of myofascial trigger points with pressure or needle therapy.
