I'm not sure what you mean by wound. Did you injure yourself or is it a type of infection? I did have different types of infections, like my eyelids swelled up, which indicates a kidney problem. The forehead is associated with the intestines (eg, wrinkles in the forehead mean your intestines are clogged). If you have a wound that's not healing quickly, I would think that means you're not getting or absorbing the amount of nutrients that you need to heal or that there are more serious issues that your body is putting energy into fixing.
