It sounds like you aren't getting it all out. From what I read the tip of the toe was just swollen tissue and blood and you didn't find any "cheesey stuff" till you got near the pad. You may have to cut more/longer in the area where you found the stuff and that may mean cutting into the pad. It's sounding like bumblefoot that spread down the toe. When it's all cleaned out there should be an empty socket where the gunk was. Go to end of toe, toward pad, and into pad if you are still finding stuff. The pad if very thick and you can cut very deep and normally have to in order to get it all out. Soaking for a long time in the warm salt water and lots of squeezing and digging helps. Just be careful to not break the toe bone.
