Hi James. About your leg´s ulcer, here in Colombia we have many options: molasses, creolina (in spanish), Fly worms and some other.... so, you can check it using Internet..... just let me know: firstname.lastname@example.org.
You might consider this strange, But i do belive in rare condition. I am from India & my friend has the same problems with mobile phones, He keeps it for a day nxty to hom, even though he doesnt attend calls, he gets swollen hands. After few days away from it its gets back to normal.
