I just read your follow up comments that tell us that you are 8 weeks post surgery and still having problems. I think you will need very close supervision to get your wound healed. Given what you posted as a photo 48 hours after surgery, I would expect that some of the areas have not healed, the wound has partially opened and you are in full wound care mode.
Once you are over the acute problems of fever and possible infection, getting the wound healed will require a lot of effort on your part. You will require both physical and psychological stamina to go through the process and it is important to remember that as bleak as doing dressing changes may be, there is light at the end of the tunnel. You may want to research whether there is a wound care center at one of the hospitals near you. It would be a good idea to visit such a wound care center, which sometimes is a free-standing facility and has access to the latest treatments.
Do not worry about the final look. Get the wound healed and then when the tissues are pliable you can think about a potential scar revision.
Good luck in your recuperation.
