Wanted to respond so you don’t think we are all ignoring you. So sorry for what you and your dad are going through. Having that surgery and the insult it gives to ambulation is difficult for anyone!! However, there is little any of us can say about a picture on a forum. If you have any questions or concern about your dad’s healing process you should call his surgeon or schedule a follow-up evaluation with them. Wish there were more guidance to provide, but that’s really the best plan.
You don’t say much about his melanoma status. As in – was this his first lesion? What stage is he? Is there a plan for systemic treatment? If any of that is unclear, I would also be scheduling a visit with his oncologist.
Ask more questions as you have the need. I wish you and your dad my best. celeste
