Three months after accident&removal of finger-belly tissue I still have a significant amount of dry eschar, now with periwound maceration, black (originally red) lines along the sides of the nail, and slight blackness beneath the tip of the fingernail. Spreading necrosis? How do I treat the periwound area? What might the swelling of the hand indicate? Is it alright to put Medihoney on the periwound skin, or will this increase the maceration? Most importantly, what is happening to the nail?
