EDP is most common in Latin America and Asia; most of the cases occur in El Salvador where the first case was identified. Cases in Europe have also been described.
The etiology of EDP is unknown. A variety of predisposing factors have been cited. These include ingestion of ammonium nitrite, an intestinal parasitosis caused by nematodes (whipworm infection, control of which produced EDP remission), orally administered radiographic contrast media, and, possibly, an occupationally associated cobalt allergy in a plumber. One case may be particularly revealing, that of a 13-year-old rural northern European truant who repeatedly ingested small amounts of a fertilizer, ammonium nitrate, to induce EDP and avoid school. Chlorothalonil exposure among banana farm workers is another possible cause of EDP
Not much help, I know....by any chance are you exposed to large doses of fertilizer? Do you work in a plant nursery, or someone in your family?
Doctor's are baffled by this disease. But let me make a suggestion. I have found that "oil pulling" works great on all skin conditions. Even ones that cause discoloration. Oil pulling involves "gargaling" with unprocessed oils. Not really gargaling, but swishing the oil around in your mouth for 20 minutes then spit it out. Not held in the back of your throat, like in gargaling. Oil pulling must be done with organic unprocessed oils that you should buy at a health food store.
I use three different oils to "oil pull" because each of them have different essential fatty acids, that our bodies need, and especially our skin. I suggest you also try all three, Extra Virgin Coconut Oil, Unprocessed Walnut Oil, and Unprocessed Sesame oil Spectrum makes the later two and Nutria makes the coconut oil. Those are products you can trust. If you want to know more about "oil pulling" go to this website. www.earthclinic.com and search and you will see a category for oil pulling. Click on that and read the testemonials. The author of the site KEN is happy to answer questions. You can post one on the website and he will respond. In fact a lot of people will respond, and you may just find an answer there. I wish you luck. Don't stop looking for an answer to this problem. You will find it. Don't trust doctors, since it is not a condition that is painful, or going to kill you, they don't pay much attention to it. You got it somehow, and you can get rid of it. Don't stop searching.
I wish you luck
