Sir, donor site of skin graft area is not healing. Now 4 months was complete. Skin is taken from entire left thigh to cover my crush injury due to accident. Doing alternative dressing by using N S for wiping wound and bactigras for healing. 700 rs wants for alternative day dressing. Many of antibiotic tablets and I V was already taken for healing. No use at all. Im already consult with many plastic surgeon. All of them said that doing another skin graft to cover the wound. But no guaranty. I want to know whats the reason. Most of skin graft donor site was healed with in 21 days usually. Please help me sir, because its very paining. During the time of dressing and also at night.
