@ZipLine-- Do you have any circulation problems because of diabetes or some other condition?
My dad has diabetes and he has diabetic neuropathy. He has very poor circulation in his lower legs, feet and toes. Even if there is a small crack in his skin, he can have serious complications from it, including infection and tissue death.
He had to take antibiotics about six months ago because of a toe infection that went out of control. His toe was abscessed and filled with pus. That's why we inspect his feet all the time. He also has regular check-ups with his doctor to make sure that everything is fine.
It's extremely important for diabetics to take every infection seriously.
