This is long, but worth reading through.
After several very helpful E-mails from Chardiver, Octopus Reef and others, the history and symptoms are much clearer.
The common thread seems to be women experiencing "skin bends" after deeper dives but within the NDL's.
Sometimes the changes were Torso, sometimes breast, but they do not normally occur with shallow or very conservative diving.
The description of these is almost identical to the description of Cutis Marmorata, a type of skin bends, from Dr Ernest Campbell's web site. (

Cutaneous Manifestations of Decompression Sickness
Pruritis
Carl Edmonds feels that this is a common manifestation of diving in a compression chamber, most likely due to the release of small bubbles from gas dissolved in the epidermis. In this mild form, no signs are visible, and the itching is temporary, mild, comes and goes and is more marked around the ears, wrists and hands. He does not consider this a systemic manifestation of decompression sickness.
--------------------------------------------------------------------------------
Patchy erythema (Cutis Marmorata)
Patchy, reddish-purple mottled areas can occur, especially around the shoulders and trunk. These are intensely pruritic and are due to a local vascular reaction from bubbles in the tissues below the dermis. This has a more serious connotation and is thought of as a systemic manifestation of decompression sickness.
--------------------------------------------------------------------------------
Lymphatic Obstruction
Blockage of the dermal and subcuticular lymphatics with bubbles usually results in edema and a peculiar pitting of the skin called peau d'orange (French, meaning skin of the orange, or, orange-peeling). This is pigskin appearance more often seen over the trunk of the body and again is evidence of a more serious form of DCS.

(Of course, attempting to make a clear diagnosis after the fact and over a keyboard is uncertain, but the descriptions match up well)
For any divers experiencing such symptoms, treat this as DCS. I can't tell you if every diving doc would recognize these symptoms, but if they fit, call the doc!
Dr Fred Bove reviewed some of the descriptions for me and noted that Skin Bends often preceded more severe DCS in patients with Patent Foramen Ovale, and suggested possible need for ultrasound studies with bubble contrast.
I'd like to learn more about what the risk factors are and the circumstances that trigger it.
This would require those of you with specific episodes to E-mail as precise a description of symptoms, dive depth, ascent rates, and any other logbook information that we could use to try to find a common thread among these women who seem to be getting Skin bends while withinb the NDL's.
Anyone with episodes matching the above, please use the private messaging function to contact me on the board, with as much info as possible, including location, water temp, exp suit, etc. (including all the details you can be sure of) Anyone having new onset symptoms matching the above should treat it as DCS until carefully evaluated by a diving Doc.
Thanks for your patience while we tried to sort out the specifics.
Please share the "skin bends" description with other divers and students.
Dive safe and painlessly,
John Reinertson
