@SarahGen-- You were lucky. I had a toenail infection that turned into a large abscess filled with pus. The only option was having it drained at the doctor's office. I also had to take antibiotics for a few days.
My doctor thinks that my diabetes is the underlying cause, so I have to go in for regular checkups now. They want to keep an eye on my feet and legs and check for circulation problems.
My blood sugar is under control but I've had diabetes for over twenty years. I think after years of diabetes, the blood vessels become damaged and foot issues become unavoidable. It's always a good idea to see a doctor when something like a foot abscess or infection happens.
