To me it appears that there is still infection in there. When you feel that spot on the webbing between the toes, can you feel anything in there?
If so, I would try first by resoaking to soften up the bottom, remove the black stuff, and clean it out again. Squeeze that area in the webbing towards the bottom, to work out any pus that is still in there. The pus will be white or creamy colored to pale yellow, and firm. Flush it out well. Sometimes it can take a fair amount of manipulation and pressure to work it loose. An oral syringe works good for flushing. Use tweezers if you can see stuff that won't squeeze out. There may be a small amount of bleeding, shouldn't be a huge amount. That can be stopped with pressure. If you can still feel anything in that area after all that, then you may need to lance from the top as well.
