Poor would healing is part and parcel for EDS. I don’t imagine the alcohol helped anything. If you could get it cultured that could help. It looks to me like what horse people call “proud flesh”. The skin and tissue grows granulated like scar tissue. In horses a vet would normally trim away the proud flesh and suture the wound closed. Not suggesting this is the case, but it’s my best “not a dr” guess. I do know there are websites online where you can post a question and a legitimate dr will answer your question. Maybe that would be an option for an educated quick consult and a new perspective.
