Hello,
This is Dr. Papaqako answering your question.
Thanks for posting on HCM.
--The black color is sign of dead cells, and it will need to fall off soon.
--The red around the wound means that it is healing in the surroundings (and that is good), but the black center do not allow the healing process. The peroxide its true that kills the germs, but also kills the normal cells, those that are trying to regenerate, and keeps the would dry. It is maybe the cause of the black area.
Yes it is healing. But, if I was your caring doctor, I would also recommend to help the healing:
a) Do not use anymore peroxide. Continue using instead the
neosporin, or vaseline, so something to keep the wound hydrated/soft.
b) Do not try to remove the black area, but for the wound to heal completely i will need to fall off. By keeping the wound hydrated, you will help the process of making it fall of dissolve.
c) If it gets pus, or more painful/swollen/red then you have to have a doctor check it, because that is a sign that it is getting infected, and he may need to give some help with removing the black area.
Hope this helps,
Take care.
