MOHs wound on shoulder not healing. What's the best way to help it improve?

As a general rule, if you keep a wound clean, moist and covered, it will heal twice as quickly as if you let the air get to it and let it dry out or scab up. It's an old wives' tale.... " let the air get to it, let it scab up... it will heal quicker." As a general rule, that is completely wrong. If you keep it moist and covered, all those good growth factors in the moistness of the wound dry up. Also, if you keep it moist, it is easier for the epidermis to resurface the wound, coming in from the periphery or from adnexal structures like hair follicles and sweat glands. Sometimes too much granulation tissue forms (i.e. heal too well) and you get too much or exuberant granulation tissue and this slows down wound healing.  In those instances we let the wound dry out. What you should do is call the doctor's office and go in and see him or her. That way they can examine the wound, make sure it's not infected and tell you what will help you in this specific circumstance. Good luck.
