I'm not even sure where to get this, but I was reading that a reccently developed treatment for soilitary rectal ulcers (and other skin and mucosal lesions) is Sucralfate, also called Carafate. it is supposed to "binds to the surface of ulcers (attaching to exposed proteins) and coats the ulcer, thus protecting the ulcer surface to some extent from further injury" and it is said to have antimicrobial properties.

any one tried it?

anyone know where to get some?

No, but I sure am going to google this stuff!
